I stopped playing after patch 13 came out because bnet2 was pretty shitty at the time, so I've been changing my play a lot since I last played. I've played very nearly exclusively terran since before the first patch came out, offracing only occasionally vs friends.
I used to always open 9rax 11gas 11orbital 11depot, and scout with that first reaper.
In tvz I'd make reapers constantly until I saw roach warren (at which point I'd switch to maurauder), walling in the nat with rax/depot/bunker and making cc after 2nd or 3rd depot (to complete the wall, depending on map). From there I'd add 2 rax and go straight to reactorport with an ebay, making a viking/medic then pure medic, adjusting my maurauder/marine/reaper mix based on what z did, then adding thors (with scv). I had a lot of success with this, basically relying on a large medic count to alleviate fungal damage. Against banelings I added more reapers to my army.
In tvp I didn't know what I was doing at all and never used any strategy concretely.
In tvt I was getting a quick port while making maurauders and getting reactor vikings asap (harassing scvs with them if no air to worry about), expoing and then getting a couple tanks before adding 2 rax. Early in the beta this worked pretty well for me, but towards the end of phase 1 wasn't consistently working.
So at the end of today, I've begun solidifying my new style, ceasing to experiment.
Now I open with 9rax 11depot 11orbital 11marine 12gas.
In tvz, I've been getting a factory asap, reactoring my rax after making 4-5 marines and getting reactorhellions, then making cc, and then basically doing the same stuff I described above. The biggest problems I've had with this is getting greedy and being too aggressive with my army, whittling down my unit count, enabling zerg to win with essentially an all-in roach/ling attack (I'll have killed a lot of drones, so this battle would decide the game, and I'll have suicided too much and/or not have enough bunkers when they come). On desert oasis I've been going thor drop instead of reactorhellion, but otherwise all things same. My other problem later on is against muta/baneling, but I think simply making tanks instead of thor once I see baneling should fix that, possibly getting a 2nd reactorfact for hellion as well.
I haven't been meching at all tvz, although everyone is of the impression it's strong. The vods I watched of terran going mech from the 17173.com world cup tourney ended in terran going 1-8, with the single win a very long, hard game; so I'm not quite sure what to think.
In tvp I've been trying a variation of Gretorp's 2rax ghost/marine build, with a fair amount of success. It does indeed do well against voidray, which in phase 1 was my biggest headache towards the end, but I've been losing against 4gate all-ins. A fair amount of the time it's definitely my fault, deciding I'm rambo and attacking protoss, losing most of or all of my army, or not making enough bunkers or something. I feel comfortable though, I just need to fix my reflex to attack as soon as my unit count hits a certain level. I've been staying on 1 techrax so far, putting my gas into upgrades and 1/2fact tanks, sometimes 1port banshee as well. I haven't really been bothering to make medics, or atleast not many. Making a lot of marines and just crashing them into the enemy, then running back drawing tank fire seems to be working, and storm/colos kill shit so fast I don't really see how medics could be useful aside from being dropships. I think I'd transition into bcs lategame with this, but can't be sure, cuz I've never had a long enough tvp.
In tvt I just started finding something comfortable towards the end of the night. Trypt told me that standard tvt is thor/maurauder opening, and while I'm not sure about the "standard" part as I've never seen a single terran do this, I did win every game I tried it on. On desert oasis I've been going thor drop instead of making maurauders.
Kulas and blistering sands have been giving me the most trouble mapwise, I'm getting pretty comfortable on the others, even desert oasis. Those two maps' backdoors are a real pain for what I'm doing.
I won't upload any replays now, because so many of them were me either experimenting or losing doing something stupid. The ones where I win aren't that good either, because often it was just my opponent not being able to cope with my build/strategy, or just being bad/failing a cheese. I'll upload tomorow's games though if everything goes solid. I was so lost in tvt for a while, I feel like I've got something I can comfortably use now in any mu on any map, so tomorow ought to go smoothly.
I'm playing so much because every job I applied to didn't call me, so my aim is to win my college tuition with sc2 tournies, with taking out subsidized loans as my plan B. I'm definitely not good enough to make that possible yet, but if I keep up my motivation and work ethic I don't think it's implausible. Tomorow I anticipate rising up my div, reaping the benefit of my efforts today. Hopefully after that I can start playing decent players and refine my play to work vs nongarbage.
