Been a while since I posted up in here, so may as well refresh things.
PSN: RCTAddict. Literally all I play on mulitplayer is Gran Turismo 6 so keep that in mind if you're gonna add me. Let's do some racing!
XBL: RCTAddict, same as my PSN. I have Gold infrequently (currently not) so no multiplayer for right now, but if I had it I'd just be playing the Forza games (or PGR 4, if those servers are even still up) pretty much.
Steam: ArDee. Again, mostly racing games (rFactor, GRID Autosport, F1 2013, etc), but I also play GTA 5 (R*SC: RCTAddict), Terraria, Starbound, Space Engineers, and 7 Days to Die.
3DS FC: 2852-7783-5434. I only play Pokemon; X, Omega Ruby, Super Mystery Dungeon, and Rumble Blast to be specific. PM me your FC if you do add me so I can add you back, otherwise it doesn't really work.
In all cases, would prefer 18+. 16+ is acceptable but I do swear on occasion so if you have "delicate sensibilities" or were raised in a religious household I may not be the best gaming buddy.
