I still think Kane is just awesome. He has got to be one of my favorite things about C&C. Besides that... The Jedi Knight series have been pretty good with their villains. I liked Dessan a lot, Tavion... she was OK. Oh, and don't forget KOTOR. The first one though. KOTOR 2 still had me going "huh?!" after finishing it. But Malak was pretty good in the first KOTOR.
