I'm curious
1) Is it the collectible nature of the boosters (as dm4hire points out) that is the problem? Would a non-random expansion deck "fix" the game? Or, no new cards at all, except perhaps in later "full" expansions like "Famine in Far-Go"?
2) Or is it the actual use of the cards in play, making powers and gear random during the game? Are randomly drawing cards during the game problematic, but okay during character creation? Would randomly rolling on a table be better (basically the same effect using a superficially different mechanic)?
As I stated elsewhere, I really like the idea of the cards themselves. I liked the deck ifor WEG's DC Universe RPG (didn't care for the game) and all the cool things about the Marvel Saga deck. I am tempted to by the Savage Worlds Action Deck at some point. However, none of those were collectible which is my sole issue with the the boosters. If it was non-random expansion decks , I would have no complaints.
