I should clarify that although I do like games that get me going physiologically, I hate "protect" type missions in games. I like trying to keep myself alive, but trying to keep someone else alive grates on my nerves for some reason.

My least favorite level in Slave Zero was the "protect" stage. Otogi had one that was really stupid. The misson was "protect the spirit." Every time I tried to stay near this fox-spirit to protect it it died. I found out that if I just ran to the end of the stage and sat there for 3 minutes and waited for the stupid thing, it would arrive untouched.
