Think nostalgia. What is the first video game that comes to your mind and why? Probably DOOM for me.
Halo 2, Coagulation. "ABlackMan Beat Down AHooker". Super Mario Kart for SNES. Turtle Town. Ace Combat 4: Shattered Skies. "'Incoming from Stonehenge, all aircraft descend to below 2000 feet.' FFFUUUUUUU-" There are more, but these 3 will do for now. If not the games themselves, then the memories of playing them with friends. Nostalgic.
