I know that game gets shit on a lot online, but I absolutely loved it as a kid. Nothing terrified us more than playing late at night and then the DUUN DUUN DUUUUUN DUN music hitting when Jason pops up out of nowhere.
The Super WrestleMania manual is funny - it took the time to note that Sid's physique was no doubt that of a daily workout regiment and basically said Hawk works stiff (stating he executes his moves with a little "extra")... and somehow they put two photos of Hawk in the "Animal" bio and two photos of Animal in the "Hawk" bio. Even stranger is that they have the correct profile photos right above them.
The WCW vs nWo: World Tour manual says that league challenge culminates at the group's major event (WCW Starrcade, nWo Souled Out, Dead or Alive's "Final Blast", or the Independent Union's Grand Prix Championship (with a little graphic making the IU / IWPG comparison a lot clearer).
I think that aspect of the league challenge got cut, or I just don't remember it.
