Its sad but true... my PS3 library (all of 4 games) cost well over $100... I haven't touched it in the months since I got into iDevice gaming.
The first premium game might well be a new, exclusive gaming franchise. Every gaming console has at least one - if it weren't for Apple being so luke-warm towards gaming they'd already have created/bought & published their own. Hopefully it'll happen. AAA games cost a lot of money to make, and that may not be possible, with them making 70c or so per game sold. More choice, more quality = good!
