This is a 3d RTS developed in South Korea (pretty much everything about the design mimics starcraft, except the actual content is more magic based) for Android devices. It runs amazingly and has a very intuitive control setup. It has 3 races. It has online play (up to 3v3 i think). It has siege tanks. It has DTs. It costs $1 in the Google Play store, and there is a free demo. There are absolutely no reasons why you shouldnt go buy/try it right now.
Everyone who has a decent phone needs to check this out asap. Here is a youtube video link with gameplay (this must be of a different countries version, but the american one is available on google play)

******EDIT**********
OK so upon further investigation heres the breakdown
Basically the Demon (zerg) race has a slower zergling, banelings, caster unit that can increase zling damage and can create zlings and banelings using resources and energy; a hydralisk that you can upgrade into a giant hydralisk with armor, a slow giant melee unit, a caster with ranged attack that can NP units or lock them down without damage, another caster that can cast a damage reflect spell and a fungal growth that doesnt lock units down, a mutalisk that can be upgraded into a heavy armor flyer that slows units with its attack,there is an overlord that is unrelated to supply but can detect, transport and get this CLOAK....also there is a nydus worm. Basically almost every element of the zerg army has a representation of some kind in this game. Also demon workers have to morph into buildings, but there is no creep or anything like that.
The Human (Terran) race has a knight that can guard which slows movement but increases defense, a ranged infantry unit thats pretty quick, a flying detector (kind of like an observer), a medic caster unit, a paladin with strong attack that can use bless and slow, a weaker caster with a high damage AOE spell and ability to block vision of a certain area, and basically the humans have a DT that has to research cloak and is not permacloaked. They also have siege tanks that can siege up, and anti-air air unit thats called a viking lol, an air transport, a fast air unit kind of like a wraith, and a BC with yamato cannon like ability. Human workers have to actively build their bulidings.
The Noa (protoss) have a zealot unit that can get a dash upgrade, a ranged infantry, a fast weaker melee unit that does AOE to light units, a slow heavy armored melee unit that can lock itself in place and get a huge armor bonus (could kind of work like FF), a heavy armor ranged unit that can hold units in place, a caster that can feedback and summon 2 different AOE dealing units, a fast high damage light air unit, an air transport, a flying dragon that does huge splash, and air caster that can heal units, slow units and cast recall. Also the Noa workers warp buildings in just like probes and can sacrifice themselves to heal other units.
Please join this game so there are more ppl playing this game is sick. Also note that when I talk about this game having "siege tanks" I mean they have unit that functions exactly the same way not that it shares a likeness with the starcraft unit. (in this case its called a steam tank)
