er, sorry...
yeah, i dropped RL CCG playing forever ago for the same reason (couldn't stand the crowd). but i still think that there's a ton of interesting gameplay potential in it. culdcept and CFC are two of my favorite games...
i've never bothered trying any of the yugioh games cos they look so ghetto/cash-in.
baten kaitos and KH COM both have some good CCG elements but they're both so easy you don't need to deal with any deeper strategizing, kind of killing the whole point of CCGing.
the random element can be very frustrating because you can just get fucked through no fault of your own, especially if a game's challenging (you won't get fucked in BK no matter how bad your hands are -- up to and including the inability to actually act for several turns in a row -- cos it's so bloody easy. culdcept will sodomize you, on the other hand.)
as for MGA, i dunno. it looks to have potential and i'll definitely give it a shot. i don't think i have any insights to offer on the game that haven't been examined elsewhere...
