I just finished the game yesterday (for the first time) on my xbox. After the Thief series (just the first two PC games, Deadly Shadows wasn't to my liking), it's probably my favourite game. Freaking brilliant!
Anyway, I was disappointed that I didn't get a chance to play a real level inside Dr. Loboto's mind. His end was kind of abrupt, just getting shot by Mr. Pokeylope.
I was hoping to fight Dr. Loboto at the end, not Coach Oleander. That was pretty much all I expected from the ending. =\
