I probably spent a good 400 hours playing Pokemon games between 7th and 11th grades, hand-leveling every single one of my pokemon up to level 100, opening my own gym, and trying to become the best Pokemon trainer in the school. That was my official childhood gaming obsession that my entire life revolved around.)
-Mario Kart 64 (N64)
-Super Smash Bros (N64)
-Marvel vs. Capcom (Arcade) (the only button-masher fighting game I was ever remotely decent at.)
-Minesweeper (PC) (Yes, I was that much of a nerd...)
And since you didn't necessarily say "video gaming," you just said "gaming...
-Magic: the Gathering. My other biggest obsession, which I played competitively all the way from 5th grade until my 2nd year of college. (Never did very well, but I spent a LOT of time building decks and playtesting them against my other decks.)
-Pokemon TCG (not that anyone ever actually played the game... the cards were more of a status symbol than anything.)
-Yu-Gi-Oh (More in late high school, but I still spent a lot of time playing it.)
I also very fondly remember my gaming nights that I had with my mom and dad, where we'd play Hearts against each-other every Tuesday night. That was always fun! And I also had great fun playing chess against my dad. (And beating him.
