This is the coolest thing I have seen yet, insofar as games are concerned, for the touch platform. If they release Riven, I won't wait a second to buy it.
Think about it: all the old school games that ran on Performas, Quadras, etc. are all capable on the touch platform, and can look nearly as good, play just as well, and capture the nostalgia market. I really, really hope this is successful and Riven gets put out there. That would be super.
And, for that matter, why can't Nintendo release Super Mario Brothers for the Super Nintendo somewhere? I want to play that again without investing in legacy hardware. I'm not that much of a purist. I have an emulator for the other games, but Mario just isn't the same that way.
Anyhow, very cool to see this come out. Can't wait to see it in person.
