I know for a fact that you're not the only person who is into Master Chief as a character/mascot, VertigoProcess. I have a friend who loves Halo, collects Master Chief figurines, and even mentions him from time to time if something reminds his Halo-obsessed mind of the series. Would you or my friend still buy Halo if Master Chief was dropped from the series, though? I think my friend Kraig would initially resist out of protest, but eventually he'd give in.
