So far, Valve has been able to successfully play (and win) games in every genre -- except for one.
“Somewhat ironically, our flagship at the moment that we spend a lot of time thinking about is Dota 2,” Coomer said. “You can definitely play Dota 2 with this controller, but we wouldn’t say to anybody who’s a serious Dota player that this is an acceptable replacement for a mouse and keyboard for that game.”
“We have an internal joke. You can play Dota with the controller; you just can’t win,” Hope laughed. “Unless you’re playing against everybody else who has a controller, and then it’s a tractable problem.”
“There are definitely games that, although playable, aren’t good enough for the existing players to spend much time playing them with this controller,” Coomer explained. “There aren’t very many games like that on Steam, though. So when we say we’ve managed to accommodate the whole catalog, there are some places where, at the highest level, that’s not complete, because of things like Dota. But the entire catalog, we still think we can call it playable. There just aren’t that many in that category.” Hope said Valve has also “been doing a lot of experiments” regarding fighting games and will have more to reveal soon.
