Brawl ever since it came out in 2008. Before that, Kirby Air Ride. Both are still great games to play with friends. Pokemon is also a great fix no matter what platform.
I was hooked on MW3 and Battlefield 3 for a while. I don't really play CoD anymore, but I'll still get on BF3 every now and then to have some fun in helicopters and jets and stuff.
Been away for a bit, but sneaking back in.
Gaming on: PS4, PC, 3DS. Got a Switch! Mainly to play Smash
