Stop making everything a fucking card game.
OK, in all seriousness this just sounds like a way of restricting how many units people bring into multiplayer. The 'card' metaphor is completely irrelevant...I think. I mean, they talk about a 'deck' but that's just your total unit supply...you aren't randomly drawing cards from it...I think...
I couldn't agree more. Card systems are such a major turn-off for me in games.
I mean hell, cards are a gaming necessity where other forms of input and interface are absent. In other words with a screen, character models/sprites, a controller, menus, and et cetera present there is no freakin' need for cards!!!!
That is, unless you are in fact playing cards within your RPG. A certain (highly addictive) FF mini game comes to mind. Now THAT was video game card-work at its best!
