Mine is a game called two worlds. Its a cheap version of oblivion and it lags on single player!!! Its riddled with bugs and glitches. You find a glitch every 5 mins.
Assasins Creed 1. Guards hated me just for being on the rooftops. Also after I beat the game I had to sit through a 20 minute cutscene before I could play again. Assasins Creed 2 was much better.
