Yes, you *can*, just as you could play Deus Ex on the PS2. That doesn't mean it's the best platform for it. I have no thing against porting to more platforms, but I think it's strange to discount the PC when it has been home to so many similar games.
This sentence makes no sense whatsoever to me. Why are you comparing a general gameplay system to an actual for PC developed game? Thats not the same thing. Not, at all.
So, doesn't your last. There are plenty of indie/artsy games on the Ipad. Why would it have to appeal to everyone that owns an IPAD? Hidden Apple policy?
