I never play games on my mobile, but I'm not averse to iOS ports and games, on my iPad Mini, which is more suited to gaming. Games like Tactics, even Theatrhythm, are perfectly fine on tablets. I have the Phoenix Wright trilogy on there, and it's plenty good on that platform.

Ultimately, I'd rather they focus on console and 'big' games. But as long as they don't neglect their 'big' games, I don't mind them doing a one or two good quality mobile games.
