Kingdom Hearts II
Kingdom Hearts: 358/2 Days (mostly because of the story line - actually the whole Kingdom Hearts story line is amazing)
Final Fantasy X (again, mostly for the amazing story)
Assassin's Creed 1 (haven't played the others yet but they seem very promising too!)
Child of Light - I haven't played it myself but I'm watching a Let's Play of it on YouTube and it's really beautiful in my opinion. I definitely want to play it myself.
