I think Monday Night Combat should have more crossovers with other games. The Team Fortress 2 crossover was fun to me.
You know what? I just though of an interesting crossover. MINECRAFT Seeing as this is an indie game, I think Notch would be more than happy to agree to SOMETHING. A Creeper/Pigman mascot is the easiest thing I can think of. Mickey Cantor lines would be pretty neat "sSSSsSSsssSSS BOOM" for headcrabs/ground zero kills. Minecraft could add an MNC painting or something. Crossovers are fun for everyone, so long as Mojang/Uber enjoy doing it, I'm sure the fans of both games would too. It's an idea I got during a nap, and I'm still a bit drowzy, so I could be overestimating its coolness.
Oh my god, a creeper mascot would be so awesome! It saying SSSSssssss some times, jumping around, and when it dies it goes "SSSSSSSSSsssssssssss *BOOM*" exploding itself A MNC painting for minecraft would be cool too, I would put it on my wall.
