Cosizzle LoK/SR. They need a reboot fucking ASAP if Lara Croft keeps getting chances.
I got lost in Ocarina of Time when it dropped something fierce chasing random ass internet secrets. Thought I could beat the Running Man for YEARS until I got a Gameshark and froze the clock at 00 and he still won.
Worst case was the original SF2: Turbo. I played it 18 hours straight when I first got it. Then proceeded to spend no less than four or five hours a day with it every day for the next 6 years. I didn't retire it until Tekken 3 hit in 98, in which point I went stupid dumb on that game until about 2000 when I rotated back to SF2T.
At one point, in case I lost my right hand, I learned to play SF2T one handed on an SNES controller. My Ryu/Ken/Sagat game is still thorough now because of that madness.
Saddest part in all of this? I started learning to use my feet in case I lost both hands. Tekken 3 stopped the madness, though. Never realize what you can do until you cut sleep out of the equation. Opens up so much free time...
