LBP, Wipeout HD, Flower, DMC4, NG, Tekken, etc. I'd also recommend Batman AA - kind of a beat them up, action title and my current favorite game.
I'd also advise you to get on PSN and download demos like mad. While not every game has a demo plenty do, with even LBP having a demo now.
You can also get demos of online games like 1943, too, and see how you fare with PSN online.
And setup multiple PSN accounts - one for wherever you live and then 1 each for the other two major stores. I'd advise having a European, Japanese and US account personally. Just pick a big company (I used Microsoft for a bit of a laugh) and use a different email account and that companies address - e.g. I live in UK so I used my details for European store, Microsoft address in US (HQ) to set up a US account and a Japanese address to set up that account.
Try to be reasonable... its easier than you think...
