I would totes play something oldschool, like those snk games like Metal slug etc. Since there is still a bundle running with these games, I imagine that people bought a couple of these for jolly co-op.

Or maybe something else, I dunno... used to play a lot of Shadow warrior 2. Or those sega megadrive games over on shteam, I'm playing them these days and they usually do feature a co-op too.

I'm ready for ideas or suggestions though.

Hey, I added you on Steam. Maybe we can play together sometime. I'm in the states but my evenings/weekends are pretty free.
