Well well well back to try and reclaim the title hey! Mario is a classic game on NES and SNES but found my love with Mario Kart on the SNES I think! COD is a great franchise too, for me, I got in around World at War time and the zombies survival mode had me hooked there, last one I really got in to was Black Ops 2 though, after that I think they kind of dwindled.
Good luck in the contest!
