very cool thread, buijon. I think what makes a great 2d fighter is the characters, it needs really cool characters like in the street fighter and king of fighters and guilty gear characters. all of those characters are really cool. and also a big part is the character's moves/specials and there voices. also the levels/fighting stages I like the ones that go with the characters, like guile, for example from the street fighter series, his stage would be a military scene. I love that!! and also the music in each level, I like music that fits the stage perfectly. and last but not least, I love color edit mode!! like (capcom vs. snk/2) color edit is really fun if you want to customize some of your favorite characters.
