Virtual Console Monday: Cartoon and Shoot Edition

I know, it's a day late. Regardless, this weeks Virtual Console release is a pretty sweet one. Here are the releases:

Mario Kart 64 - N64 (1000 Points)
Contra III: Alien Wars - SNES (800 Points)
Bonanza Bros. - Genesis (800 Points)
Comix Zone - Genesis (800 Points)

This makes two consecutive weeks with a solid first party offering. Thanks Nintendo! However, Chris pointed out (and I concur), that Mario Kart 64, while not being awful, is the weakest in series. Oh well, Contra III is a blast. I never did have a Genesis, so I can't say I've even heard of Bonanza Bros. or Comix Zone. So dear reader, tell me, they worth anything?
