DotA 2 for your Android or iOS device sounds far out, but mobile technology is moving at a fast enough that it might be possible.
According to Valve boss himself, DotA 2 may be a possibility for mobile platforms down the line. Speaking to Kotaku, he stated that Valve was already conducting tests: "We were working on getting DotA 2 running on some tablets.
"That ended up being kind of a disappointment. But the good news is that tablets are getting faster very quickly, so I think we'll get the kind of performance we want and other game developers want in the near future."
Though DotA 2 may be fast paced, as Kotaku's Jason Schreier points out, it doesn't require quite as much clicking as does say, StarCraft. Hence, DotA 2 might just work out for the likes of iOS.
The only question then is whether or not DotA 2 mobile players will be able to play with those playing on PC.Then again, whether or not DotA 2 iPad will actually even be a thing remains to be seen.
