Following on from
here, here's an updated list:
1. Final Fantasy XIII
2. inFamous
3. Valkyria Chronicles
4. Atelier Rorona
Yes, apparently I just need one more. Or maybe two more; I hear that Valkyria Chronicles 2 is on the PSP, which I already have, and if the story doesn't require knowledge of the first one and the gameplay is better, I'll probably get the second game and leave the first alone.
As might be obvious, I'm very attracted to cutesy anime graphics, but I should add that Disgaea and its sequels turned me off on the super-grindy aspects.
Atelier Rorona is there mostly because people have been suggesting it to cure any Recettear-induced cravings for item shop fun.
I'm still not convinced about Little Big Planet (2) and other games which need downloadable content, because I'm not sure if I can connect my potential PS3 online. I know it's supposed to be So Easy Anyone Could Do It, but I've heard the same about my PSP and I still can't connect that.
