Dreamcast and Gamecube, I think, no idea how many hours I put into those consoles. I was obsessed with Phantasy Star Online for years, from 13 - 16, I played it every day on weekends and after school. I can't imagine how much money my dad put into it because it had a paid subscription when it was put on Gamecube, 15 bucks a month. After I turned 16, my appeal for skateboarding took over everything and then Playstation 2 became my main focus. Tony Hawk's Underground 2 probably stole a good 500 hours from me from playing online and such, maybe more, I'm just guessing. Nothing has come close since, but with all of life's interruptions, how could they?
