The best moments of my childhood took place in an arcade. It was when I was first exposed to Mortal Kombat and how I would spend hours and hours mastering every move. Then it moved to Street Fighter II, then X-Men Children of the Atom, then X-Men vs. Street Fighter, and then to the greatest arcade game of them all, Marvel vs. Capcom 2.
Of course I also played the classics like X-Men, Teenage Mutant Ninja Turtles, Gauntlet Legends, The Simpsons, NFL Blitz, etc.
