i found some beta stuff about THUG2 and THAW, i forgot most of it since it's been like 4 years since i saw the beta trailer for THUG2
THUG2The CAS would contain all of the THUG1 objects
It contains most of unused specials
I think Bucky Lasek was supposed to be in this game
Most of the pros had some THUG1 Clothes (example, Chad Muska was wearing the circa logo trucker hat)
THAWTony hawk model was the same as THUG2, but was recolored
The pros were the same appearance as in THUG2 (i think)
Originally THAW would have THUG2 ammo (Beads, apples, tomatos)
The HUD colors were different from the final build (it was pink in the beta)
Edit:i found some demos from PS2 version of THPS4/THUG1, Shawn Murray's Pro Wakeboarder in THPS4, and MTX Mototrax in THUG1, never really played them
