Never been to a live event. My brother is always trying to get me to go but I pretty much won't. I know it's probably a really awesome and exciting atmosphere (or so I hear), but I've also heard that unless you have good seats, you can't see jack and just end up watching the big screen. And I don't watch MMA/UFC to hang out with a bunch of raving drunkards wearing Tapout who want to fight in the parking lot. Eventually I'll go to one for the experience, so I can say I have gone, but for now, bleh.
My first UFC ppv was probably a pirated copy of one of the UFC 80's. I had been into boxing a bit and only wanted to watch MMA to try to learn a little hand skills by observation. I pretty quickly realized that boxing boxing and MMA boxing aren't the same though. So instead of continuing as a boxer, I turned into a MMA fan, and not long after that first pirated UFC event, I started taking kung fu and actually ordering the ppvs like a good boy.
