At some point, all of us, I'm sure, have run into someone in an online game who we think is cheating.  Maybe they lag at oddly fortuitous moments,  maybe their gun is firing way too quickly, whatever--we're sure something fishy is going on.  While we may not be correct in our assumption all the time, a simple internet search on the subject yields proof that it does happen--after all, people don't set up businesses to produce modded controllers and the like if no one is buying their product.  So, there's no question that cheaters exist--the question is, why do they do it?

Myself (and I most gamers I know) don't derive much satisfaction out of a win if the fight isn't fair.  For example, when me and a friend were temporarily obsessed with Soul Caliber a while back, one or both of us would sometimes fail to notice the handicap feature was active on a character.  When that happened, whatever wins or losses occured during that period were automatically forfeit.  There was no gloating, no bragging, nothing--the fights felt like nothing so much as a waste of time.  

So, in light on my complete lack of answers for the question I've posed, I leave it to you, fellow Bitmobbers.  If you've cheated, if you knew someone who cheated, if you simply have some enlightening thoughts on the subject, leave a comment.  Once I have enough probable answers on the subject I'll update this post with your insights.
