Just catching up on this thread - Bernie, in my experience, those open world games played just fine. However, if RPGs are your thing you may not have enough time to see them all

Here are some of my PS3 favs that still stand out in my memory:
RPG
3D Dot Game Heroes
Dragon Age: Origins
Elder Scrolls 4 or 5
Eternal Sonata
Ni no Kuni: Wrath of the White Witch
South Park: Stick of Truth
Star Ocean: Last Hope International
Valkyria Chronicles
Action
Castlevania: Lords of Shadow 1 or 2
Darksiders 1 or 2
Dead Space 1, 2 or 3
Fallout 3
God of War 3
L.A. Noire
Last of Us
Red Dead Redemption
Resident Evil 5
Saints Row 3 or 4
Uncharted 1, 2 or 3
Puzzle/Thinker
Beyond: Two Souls
Catherine
Heavy Rain
Portal 2
2D/Platformer/Retro
LittleBigPlanet 1 or 2
Midway Arcade Origins
Rayman Origins (Legends is even better, not sure if it got a PS3 release)
Sonic's Ultimate Genesis Collection
If I had to pick one game from the entire PS3 library that you ZOMG MUST PLAY, I'd go with Ni no Kuni. It's magical. I loved it. And lucky for us, a sequel was just announced to be in the works
