What kind of features did it have?
You had your standard one-on-one, tag, handicap, triple threat, battle royal and elimination matches
You can set the match rules to reflect both Japanese and American wrestling styles, as well as shoot style and MMA. Or you could mix and match the rules as you see fit.
From the main menu before you start a match, you could set what arena you wanted, what ring you wanted, what ring announcer you wanted, what referee you wanted, how fast the match speed was, what company the crowd was a fan of, whether you had a ramp or not, turn commentary on or off, and choose a play by play guy WITH the commentator
That's just the match stuff. You could also had your basic story mode where you fight opponents to unlock stuff. There was a match maker mode which was basically a GM mode for 5 different companies. There was a title match mode where you fight for the titles of those five companies, and a tournament mode.
Of course it had a CAW mode, but you can clone any wrestler in the game. You could set your CAW's fighting style, his popularity, and set their A.I so they could wrestle accurate to who you were creating.
Goddamn shame it was Japan only
