I have been raving about this series for years. The roster, move list, character creation options (minus the actual looks) are quite insane. The fact that you can not only make a wrestling style character, but make a MMA character and fight with MMA rules is awesome. You can make ANY move your finisher/trademark move. The whole chance of getting a critical on your opponent with any move is also awesome. The fact that you can set a voice to your character and choose which move/taunt you want him to grunt/scream out a catch phrase on. This game is just all kinds of awesome!
EDIT: Here's a pretty good match:
YouTube - Fire Pro R: AJ Styles vs. Milano Collection AT vs. KENTA
You can see that AJ Styles lands a critical on KENTA with the Styles Clash and it's pretty much over for him after that. Just wish he would've landed at least one Go 2 Sleep.
EDIT 2: And here's the awesome trailer:

Jam it back in, in the dark.
