Thought this was "Worst CRPGs"?
Oh well, console games into the mix as well I suppose.
Vampire Bloodlines : Horrible performance, bugs, glitches, story doesn't hold up too well towards the end, boring combat.
Neverwinter Nights I : Toolset, onlineplay aside... I wanted a good single player RPG, I didn't get that. I got a tired generic story with no real depth.
Dungeon Siege I & II : Your typical Diablo style killer hack and slash RPG. Boring.
Star Ocean 3 : Just bad all around. Story is... dare I say it, stupid? Hole first part of the game has absolutely no baring on the plot.
