Everybody knows Street Fighter. After Mortal Combat, this one's probably the most well-known fighting game around. Well, this's the second one, sequel of SF. It's generally the same as all these games. There is a story mode, in which you can choose which character you play, then beat up enemies, one by one. There is also the two-player mode.
The story mode lets you choose which character you'll be fighting with. After that, you'll have to beat up the other fighters and get a typical, brainless, taunt after two wins or losses. When the taunting's finished, you'll just fly off to the next challenger. There's no real story in story mode. Beat up one guy, then get to the next one. After beating up the seven first main guys, you'll get another set out of which you couldn't choose before. They are more difficult than the previous ones, but there's no real difficulty increase between two of each set. If you're looking for a bigger challenge after going through story mode, just increase the difficulty level. Personally, I wouldn't recommend the easiest, as it's as easy as cutting butter with a knife.
The two-player mode allows you to beat someone else up or practice your moves on a dummy in case can't find someone else to play along. Choose two characters from the basic set, then a background in front of which you'll fight and you're ready to go. This's perfect for beating up your bro when he stole your candy without your parents getting mad at you.
All by all, Street Fighter II is a fun game. It brings nothing new, even for its time, but at least it looks pretty and the music is ok. This critter's perfect for venting your frustration off on.
