Are there any good Android games? That's a matter of opinion I guess. The OUYA may not be able to compete with the PS3/4 but it's not likely going to try. It may however kickstart a bunch of new games and cater more towards the smaller indie developers.
Overall, I like the idea behind OUYA, and it certainly has a chance of doing well.
Well, it will be highly hackable but that will appeal only to the nerds. For everyone else, the console will have a free-to-play policy, meaning, all games sold through OUYA's store must have a free-to-play mode. Sales will be generated in other ways, for example, downloadable content or extra levels or whatever. That plus the fact that most Android games are dirt cheap, could be quite appealing when you compare it to the next gen mainstream consoles which will likely be sold for $300+ and games will be roughly $60 or more. What would be genius would be if they find a way so that you can play your OUYA games on your Android tablet/phone as well. That way, you buy a game on OUYA, and you can play it on your phone while you ride the bus. If they can do that, then that would be quite the killer feature. And I see no reason why that can't be possible, it would only require an OUYA Store app on Google Play.But I don't see anything unique it offers.
