David, other than the fact he's a plumber. He seemed to me like the coolest character, especially among the other men. Kevin was decent, yet gave off an immature vibe, to me anyway. Jim was a wimp, to put it nicely. George was alright, but kind of bland. Mark was cool, I guess, but I'd still go with David.
When it comes to the females, I liked Cindy for her looks, Alyssa for her character. If I had to choose one as a favorite, I'd probably go with Alyssa. If it were a movie, Cindy would probably be that eye candy girl that would get killed early, while Alyssa probably has more brains and would be a survivor.
And yeah, I'd love it if they remade these games with more current graphics and made certain aspects of the game more similar to the earlier games of the main series, but since the Outbreak games (to my knowledge) aren't really all that popular, I doubt it'll happen. Plus, they need to remake RE2, 3 and CV before they do this.
