Well, Halo 2 IS indeed amazing. Best game ever made - in my opinion of course.
I remember a 1 Flag game on Headlong in Matchmaking. 4 versus 4. We were playing normally until the very last round, where it went into sudden death. The thing is, Halo 2's sudden death lasts forever until nobody is near the flag. So this guy who got the flag hid. Everyone on our team was searching the entire map - we had already won, but we had to play a bit of hide and seek to get our win! It was actually not really annoying, it was awesome. Everyone was superjumping around the whole map, exploring the buildings, looking around for him. I think we searched 30-60 minutes before the flag carrier returned to the flag spawn where we finally found him. It was awesome :D Would be a nice addition to CTF etc.!
I don't have much time, but I'll certainly add some more stories later! Keep this alive, this is an awesome collection of awesome!
