Topic: Specific games to play multiplayer on!

Hey, I know there is a healthy-ish online scene for the more popular nintendo games. But there are a ton that I can't find people for, so I'm hoping to use this thread for specific games where I'd want to play with someone with. Feel to do the same in this thread.

I'm looking for people to play:

Megaman Battle Network Collection
Advance Wars ReBoot Camp
Ultra Street Fighter 2
Super Mario 3D World
Civilization 6

And on NSO:

Super Mario Kart
Sonic The Hedgehog 2
Killer Instinct Gold
F-Zero X
Soul Calibur 2
Pokemon Puzzle League

I hope I find you!
