Failure.
No communication about what is going on with the game.
refusal to support it - and that's not just no OP, but refusal of OP.
restrictive gameplay rules (very limited use of trainers, only 1 style of play area).
Prof Clay, Milton Bradley, and similar companies which don't establish player bases for their games, don't need to. Their games are staple games in homes. No home goes without a Monopoly, easy bake oven, Candyland, etc at some point in time or atleast have access to it. TCGs are not staple games in homes.
