Diablo and Diablo II probably over 10,000 hours when I was young,
Starcraft
Warcraft and Warcraft III
007 Goldeneye 64
Final Fantasy VII and Tactics
Diablo II and FFVII and Tactics took up so so so much time from age 12-15. I mean omg I would get home from school at 3 and play Diablo II until about11pm EVERY SINGLE DAY for about 3 years straight.
