I loved this game when I was a young'un, I played this, Alpha 2, and Tekken 3 with my older brother and have been obsessed with fighting games ever since. Capcom's PS1-era spritework is immaculate and even modern indie games struggle to match it.
I'm biased in favor of Charlie Nash but I have to give it to Cyclops because it schmooves too fucking hard even though I hate him as a character. Shame him or his theme didn't survive for Marvel 3.
