Could you imagine how much bank they would make if they made a Marvel thing like that? That was focused on the mainstream rather than minis gamers or whatever? Marvel Descent would basically be a license to print money, even more so than all the other cash machines FFG currently has cranking 24/7 (ok, maybe Star Wars minis would still have it beat
).
Man I would love a good accessible-but-deep licensed tactical Marvel game. Legendary scratches the itch, and they actually do a really good job of incorporating theme into the cards but at its heart it's really a eurogame (in the sense of Dominion, just with some extra layers of rules and mechanics).
