RE4 (GC) i had completed numerous times.
Marvel Vs. Capcom 2 (arcade & DC) more times than i can count. Working in an arcade helped w/ beating the arcade version over and over and over again
Link To The Past, Super Metroid, SF2, Mario series, Final Fantasy 2(us), Earthbound. So many replayed memories.
Hmm... now that i look at it, thats a lot of Snes games, mainly. Yea, that was the last system i owned for which i TRULY cherished the games. (young, parents purchased, no REAL piracy for home systems at that point. Ahh, those were the days heh)
EDIT: oh, and there's TONS for the Nes that i'll go back and breeze through now. OH. Deja Vu for the Nes. That one, i could have very well beaten more than any other. Back in the Nes days, too
