My biggest question is this: turn-based, or real-time?
I should probably explain the dynamics of the game a bit more. You play in 3rd person perspective, controlling a sorcerer of some type who has a deck of cards (hence the CCG element), and uses them to attack the opponent. Across the "battlefield" is another sorcerer who is doing the same thing. Creatures are summoned, spells are cast, etc..
In games such as Magic: The Gathering, I didn't really care for the way spells were dealt with in the turn-based aspect. I think that if I go for the real-time route, the game will be (somewhat) more realistic, and probably more fun, but I'm not sure. I don't want the wrong type of play to destroy this :-/.
Turn based would allow more tactical strategy I think, but real-time would allow for faster action and quicker game-play.
Which would you all prefer? I'm stuck between the two.
I'll post some mock-up diagrams later to further explain the layout of the playing area.
