this really isn't all that useful
spells are very important. ghost EMP craps on any toss army. especially if it has immortals

Hellions might not be cost effective by themselves, but they force an opponent to respond in a particular way (ie zerg getting speedlings and lots of lings instead of drones), are very fast and strong at harassing, and can cut apart light units, allowing your heavier units to be more cost effective.

Gas weighing could be done through a map availability analysis, or mine rate.
(for example, in BW, there are nine mineral patches and one/two gas patches per main base. A weighted ratio could be 1 gas = 9 minerals?)

Yes, 1 gas is much more valuable than 1 mineral. Gas is limited to around 224~ mined per minute per base whereas minerals are mined at up to 800~ per minute per base not including mules which add a LOT of mineral mining. Lots of high tech units require a lot of gas and you can see that now 1 gas is a lot more useful than 1 mineral.


You changed your point by saying in the end that one vespene is more useful than one mineral. This may be true, but does not determine value. One resource is one resource, equally valueable.

Perhaps a resource's value manifests from the time one invests into accumulating it: the time it takes a worker to go back and forth; that time reinvested into a new worker; and so on. If the inherent nature of the game forces players to wait more time to collect gas than minerals, then each unit of gas takes more time, respectively. In this case, gas holds more value since it represents more time.

If this is true, then you should take no difficulty in refuting my inferences, as I've asked. I know I have been unable to implement such things as range and splash damage. You keep throwing this red herring at me--saying nothing of my actual inferences (the thing I'm asking you to refute).

These values, they can help a lot but some of your conclusions about each units based on this data is just not accurate. For example, Battlecruisers are amazing but you need a fusion core, time to build the battlecruiser, and the upgrades you would have for air units at the time. If you transition from bio or mech to battlecruisers, you wouldn't have 3 / 3 upgrades for air while your enemy most likely would.

Thors are strong units that do tons of damage to air and ground units, yet again time and the slow movement of Thors make them weak in some situations compared to a Bio army.

Hellions are great for killing workers. You're values don't factor in speed, and ability to micro them via kiting. Hellions under micro can kill an entire expo full of drones with the pre-igniter upgrade.

As for spine crawlers, they might be cost effective, IF they moved and attacked. They can only attack while static which would explain why they're so strong. They are also limited by creep I think?

Phoenixes might be slightly better against air units than the stalker, but stalkers are from warpgates which can be easily produce since you don't need make stargate. It's also easier to transition from stalker to phoenix.

Some do make sense though, like how facing a bunch of armored units immortals and void rays will crush all. Massed voids will probably crushed every Terran armored unit except for a bunch of Yamato Cannon Battlecruisers (even then you'll need a crapload of BCs). But if Terran had a Marauder + Ghost army. Sure there's a bunch of armored units so i must use Immortals. You will get killed since Ghosts will just emp you're immortals and they're basically dead meat (dead metal) to the marauders.

This reminds me, spells of several casters in this game would make me to believe that they are more effective than this data would suggest. AoE, how many units are caught in the spell, the cooldown, the energy per damage ratio, number of times attack can be used, if it does any damage at all (sentries) etc.

"I don't play Terran, but what's up with the Hellion? Seems pretty lame."

if you're gonna try to write something analytical, why say shit that isn't true/ambiguous. lame can mean that you hate them because they're too great or that they're shitty.

He didn't say useful, he said valuable. Besides, that's like saying one supply equals one gas. One resource is one resource, equally valuable, right?

On that note, I'd suggest adding supply costs to the total resources: (supplycost / 8) * 100 = mineral costs for supply.

I wouldn't listen to him. You can't infer any of what he suggests without creating a SC2 model identical to the game and players involved, which would be a ridiculous undertaking, not to mention completely pointless. Just stick to the units-in-a-vacuum if you want to extract useful data.

on the topic of the hellion:
1. it is very fast, which is one of its main strengths
2. it has line splash, effective both when harassing and in battle, especially now that they auto target at 6 range
3. it relies heavily on the pre-ignite upgrade, whereas you stated data comes pre-upgrade

How do you factor in superior micro mechanics into cost effectiveness? A unit is as effective as the player makes it. It's nice to see all the numbers, but this isn't really useful as there is a large concept in Starcraft 2 called micro.

The chart has some nice info, I think a nice addition would be info on marauder+marines while stimmed.

However, looking at units from a pure DPS standpoint leaves out some very important factors.

Seems pretty lame.Except against light units, Phoenixes are only very slightly a better answer to air than Stalkers.

Of course, phoenixes are very fast and maneuverable and also have the levitation spell.

I don't play Terran, but what's up with the Hellion?

The hellion is a mineral only unit, and terran players often have a surplus. Additionally they have line of fire and are fast. Despite their deceptive placement in your table for DPS, top players like qxc and TLO use these units very often in both TvZ and TvP.

So again, the data is useful. But what is great about sc2 is that DPS isn't everything, there are many variables.

Actually no, you're the one under burden of proof here. The very fact that you're making blanket statements from simple dps/R values shows that you don't understand the dynamics of the game, which include other factors that I've listed. Your conclusions do not take them into account.

You also did not implement things like unit abilities such as cliffwalking, flying, burrowing or just speed, all of which are crucial to giving recommendation regarding counters.

Your inferences are wrong because they were made using incomplete information, and if you still don't understand that refutes several of them, you're either trolling me or haven't played a game of SC2 in your life.

I like how 60% of the the posts so far are people pointing out the 100's of varibles, even though the OP already stated this is a strictly number based chart and he/she understands that the varibles are impossible to account for.

Take it easy on the guy.

Thank you again for reiterating this helpful point. I've recruited the help of other forum members and have revised my inferences to take these other factors into account. Hopefully, with time, I can strengthen them further.

Perhaps the biggest number I would like to see in a chart like this is HP/resources.

Also, dps should be two collumns: vs 0 armor and vs 1 armor, that way you can see the effect of 1 armor difference.

Very interesting read. Even though like you said this should not be considered as "do only this unit" as it doesn't take into account some battle limitations like ultralisk having huge problems actually inflicting that damage and mutalisk's harass ability due their speed.
But still fun to read, thanks

Are some of the units missing btw?

Funny, I originally had HP/resources, but removed it for simplicity. I'll add it tomorrow as well as look at armor (I still don't fully understand armor). Thanks.

Yes, if I have time, or if someone else comes up with reliable ways to compute tricky units like Carriers, I'd love to add them.

On resource comparison, I don't think saying 2.5min=1gas is wrong for such a generalized table, just make sure you state somewhere that is the conversion being used.

This chart doesn't need to cover every little possibility in the game, but there should be a small, but notable difference between roach dps and queen dps vs ground. Queens hitting 4x as fast as roaches to do the same damage makes armor 4x as effective. That is a big thing to miss IMO.

In game armor calcs are easy.

1 armor = -1 damage.

So a roach hits a zealot for 15, not 16, while a queen hits for 2x3, not 2x4.

Do tell. Why?

u ever have a situation where you would trade 500 gas for 500 minerals? I never o.0
I did have situations where I would trade 1k min for 1k gas... (fucking high templars...)

I came across this nice google spreadsheet a month or so ago. It's slightly outdated, but most of it is still relevant. I think it's worth a look. This guy uses 1.25*gas cost to determine it's equivalence in minerals. It also has calculated the dps/cost, splash, upgades, armor types.
