Diablo 2 probably the single game ive logged the most hours in and pry my favorite
i was a big fan of point & click adventure style games especially from lucas arts such as the Monkey Island series, Full Throttle and currently playing a game called The Dig which is a big flashback to my childhood.
Earthbound, Chrono Trigger, Final Fantasy 1-4, Secret of Mana, Secret of Evermore, Illusions of Gaia, Breath of Fire, and Phantasy Star were all really big games for me as a kid too. Was big on that classinc RPG type games.
Have played almost every Zelda and Mario games ever with beating the majority of them.
And then of course you have multiplayer online games like Modern Warfare 2 (or black ops for zombies), Overwatch, Halo 2/3/Reach, Rocket League, Madden, 2K, Chel, Fifa. Was always big on nfl street as a kid as welll
