While the breadth of "Torg" was one of its most exciting features, it could also cause significant problems. Because the scope of the game was so broad, and it incorporated such a wide variety of skills, the game became unwieldy to some players. Further, in some cases simple rules given in the basic set were thrown out or expanded in sourcebooks, so that players moving between campaigns sometimes found the rules were not what they were used to; even some of the character templates from the boxed set were not completely compatible with the rules in the sourcebook for their home cosm. This breadth of scope also served to ratchet up the game's expense: each of the game's realms was detailed in its own sourcebook, and those sourcebooks included rules that weren't covered in the main rulebook. For instance, if a character wanted to build his own magic spells, the player needed to own (or at least have access to) the "Aysle" sourcebook. Likewise, psionics were covered in the "Space Gods" sourcebook, martial arts in the "Nippon Tech" book, pulp powers and gizmos in "The Nile Empire" and "Terra" sourcebooks, and cyberware/bionics in the "Cyberpapacy"'s. Note, however, that if a Cyberpapacy character wanted to hack the GodNet, they needed yet another supplement for those rules. While this allowed a group to take their game in any direction they wished, it made it difficult to keep up with all the rules. This is especially true because long-term campaigns tend to lead to cross-genre characters, such as mages with cybernetics, or espionage agents who learned the Occult. It reached a point where even published adventures would forget, ignore, or skim over previously established rules.
