halo 3-probably a good 10 times, mostly co-op.
Pokemon Red/Blue-probably 10 times. Some people enjoyed trying to catch them all. But when I was a kid I would always restart as soon as I beat the game and try and beat it again with a completely different team.
Halo Reach-twice. Once Solo and once Coop
Super Mario Bros-Dozens of times.
Super Mario World-Dozens of times.
Crash Bandicoot-around 3 times I think.
Wind Waker- Twice
And thats about it, unless you start counting games with pseudo campaigns like mario kart/super smash bros
