I'm Terrible

at Street Fighter.  Honestly, I'm not sure why I keep buying fighting games other than Tekken and Mortal Kombat.  I'm just really bad.  For the most part though, I enjoy playing it.  I'm not expecting to be good, nor am I expecting to be able to compete online.  I guess I just like the challenge even though it can get pretty frustrating sometimes.  
 
Anyone else have any games that they really like, but completely suck at?
