If we go by how many times I've gone back to them...
Castlevania: SOTN, FF7, Megaman X4, Spyro 3(I 100%ed that game 4 times in a row when I got it. I loved it that much. Haven't been able to beat it since, and I've had my copy for nearly twelve years), Spider-Man.
If we go by sheer overall enjoyment, it changes dramatically.
SOTN, Megaman X4, Spyro 3, Xenogears(My pick for overall best jRPG ever) and Blood Omen: Legacy of Kain(To date, it's the best voice acted game).
Yes, changing 2/5ths of the list is enough to qualify for "dramatically."
As you can figure out, my gaming tastes back then were more for Japanese games. Nowadays I tend to play PC games so it's usually western games that get played.
