Not just graphics, but in terms of Create A Wrestler options (it didn't have the same variety as Virtual Pro Wrestling 2 in terms of outfits, but it did have props, more moves, songs etc).
Also, it featured an in-game store where you could spend your bucks earned from either the 100 Man Battle Royal mode or the Storyline Mode, which followed storylines for all the belts at the time.
Plus it featured backstage areas, which wasn't a thing in previous games.
