You may notice a bit of a theme to these games:
-Tales of Vesperia (I actually played it fairly recently, but it hasn't taken much to make me constantly want to play something with a little more action)
-Wild Arms 5 (want to play it, but I need a PS2 to play it without it crashing every 5-10 minutes because it's not entirely PS3 backwards compatible)
-Shadow Hearts Covenant (this I can play on my PS3, but the game's just so massive and to be honest rather ugly and slow)
-Star Ocean: The Last Hope (like the above, also so absurdly massive and guide-centric I never want to play it)
-Wild Arms 4 (see: Wild Arms 5)
Honorable Mention: Final Fantasy Tactics. I got it because it has such high acclaim, but I've found over time (especially after playing Valkyria Chronicles) that I despise turn-based, grid-based, Tactics Ogre-cloning Tactical Strategy RPGs. That game is just such a chore to play, and the payoff just doesn't seem worth it.
I own all of the above, but I just never want to play them (or I can't play them).
