Street Fighter
1.Pretty good graphics.
2.Really different/unique characters.I really like that aboit SF,all of them are completely different.
3.Brilliant story line.
Well,as you can see, SF and Tekken are,in my opinion, equally great. Graphics,Story Line and Characters are the base of an awesome video game,like I always say.
