Just recently I bought a PS3 bundle with GTA5. I left my 360 at home when I moved to another country (Germany) and didn't want to have to wait to play GTA. Now, I want to play all the other great games I didn't have the chance to before.
I will definitely be getting Journey once my internet connection is set up in the new apartment, I already bought Heavy Rain in Gamestops pre-owned section. I'm also looking forward to playing MGS 4, Uncharted 2, HD remakes of ICO and Shadow of the Colossus etc.
Please, enlighten me on all the other games on PSN and retail that are worth getting and experiencing on PS3.
