Irrational did what they were told
Irrational was't told to put bugs in the game. It wasn't told to make horrendously stupid AI even on the highest difficulty setting, and I seriously doubt that Vivendi wrote the inane story for the single-player game given that the Irrational developers talked about it at length in pre-release interviews.
Vivendi may have chosen not to pour any more money into the game after release, but Irrational actually created the game and did a damn poor job at it. Irrational even had a second chance to fix the problems in an update, but instead released something which fixed almost nothing.This comment was edited on Aug 31, 20:29.
