I've always like 2D fighters better, especially since they create more instances of being fast whereas 3D fighters always feel sluggish and slow to me. Its not that I hate 3D fighters but very few have ever really impressed me too much. Whereas SFII has kept my soul for years and games like MvC, KoF, GGXX, and my current fave, Tatsunoka Vs. Capcom (sp?) have always found ways to bring me back.

I guess there just hasn't been a 3D fighter yet that has made it up to my elitist fanboy standards.
