Houdini. Such a beautiful looking game, awesome theme, and decent code (straight jacket multi-ball). The geometry was so off on this game it was a shame, should've been a wide body. I love the magic theme, but just could not get into the play of those ridiculous tight shots.
TSPP left fast. Call outs were terrible. Never got the love everyone puts on this game. Deep code on a nails on the chalkboard game - no thanks.
NIB X-Men LE also left fast based on call outs. "Here's an exxxxtraaaa baaaaaallll" Magneto voice still in my head. The voice actor call outs ruined a fun layout. Don't get me started on Beast or Storm. My stomach still hurts thinking about it.
