I've owned every popadiuk game except ToM and none of 'em are worth reproducing.
WCS is fun, if basic, but they made plenty of 'em
ToM is OK, if exploitable, and they made plenty of 'em.
ToTAN is a beginner level game and gets real boring real fast - no legs at all.
CV is a 3 shot game (left orbit, RM, ramp), and a PITA to keep running on location.
SWep1 was an appropriately bad game for a pretty bad movie.
CGC is gonna do what CGC is gonna do, but IMHO any of these is a waste of time and resources.
