Here's my idea:
First off, get the PS3 version finished and released...
PSN download, just like any other game. Whether it goes to the network or game section? Don't know. Don't give a damn. Would prefer it to just go to my game's menu so I can put it in my PSN folder though.
Keep the game free like on pc. That alone would give alot of people a reason to try it. The PC version get's revenue from ads and micro-transactions. Don't see why it wouldn't work on PS3.
Most importantly: Full integration with the Friends menu. Make sending messages, voice calling, meeting up with friends etc. AS EASY AND SIMPLE AS POSSIBLE. Would also be nice if we could get some in-game custom soundtrack support for this 
If they can do this, the game will do just fine.
