You said "collectible cards."
That works in scenarios where there is competition.. but not in scenarios where there is not. Hasbro already has a competitive collectible D&D . It's called D&D Minis. What you're talking about is, again, diluting and constricting a market.
Avalon Hill tried a Collectible game in a non-competitive environment using Stratego Legends. It failed. TSR themselves tried to market a collectible dice game, and it failed.
Now you think, really, that the market leader in RPG, the market leader in board games, and the market leader in CCG .. are somehow going to constrict their RPG market, constrict their CCG market.. over a non-competitive game?
Let me ask you a question. What would stop a group of players from simply using Proxies in the case of the "collectible cards?" Because what stops Magic players from doing that now is tournament rules.
