OK, you are correct. It would be great, than you have to roll many dices in a LCG. That's to random. I use it as proxy for an RPG like card game. But that wasn't a good one.
I was talking about setting. The LCG itself would use no dice, obviously.
Then it should be a co-op game in the Fantasy or 40K setting, it have to be a group with a common goal - so it is the RPG setting. Why shouldn't that work?
