It's which one it is, like the first one was UFC 1, the next one was UFC 2, then UFC 3, then so on and so forth.
UFC, i was playing that game too :)
UFC has always been UFC
1993 can be considered the year when UFC was found because the first ever UFC event - UFC 1 was held on November 12th 1993 at McNicholas Sports Arena in Denver, Colorado, USA. After this UFC has been hosting regular events which are conducted every few months. Currently UFC has a monthly pay per view kind of schedule plus a host of other TV fight schedules like UFC on Fox, UFC on Fuel TV etc.
Many UFC fighters train at high altitudes in places like New Mexico and Colorado.
The schedule for official UFC events can be found at the UFC website. There, you can choose what country to look for events in and what kind of event (TV, appearances, press conferences, etc.) you would like to see.
ufc 101, ufc 102 etc. are events that are put on by the UFC. So it's like world cup 90, 94, 98. However, it's not a tournament. UFC undisputed is just the video game.
ufc becaue in ufc there is mixed but in boxing there isnt.
The next UFC is UFC 118 on Saturday August 28th, 2010
