First and foremost I was always a local \'Capcom whore\'. This was before Sega went third party! So, now I have to pick which one is my favorite.. AH, its a tie.
Capcom and Sega.
I\'m sure Sega will continue to deliver excellent games and Capcom will always rock.
By the way - Wesker to answer your question on "who else would release a big game in the US and Japan?", Sega would. They did it with Sonic Adventure 2, if I remember correctly!
