So has there been any information on the conversion rate of actual money to in-game currency, and how much characters will cost?
The Founders Packs that you can pre-order each come with a set amount of in-game cash - the Premium packs that unlock 4 characters come with $30 worth of "G" for example, but there's no indication of exactly how much "G" that equates to, and how much that will buy you in the actual game. One character? Two?
$60 for a premium pack that only comes with four extra characters seems steep. Especially since you only get to choose ONE of the free characters when the game launches. So pre-ordering for $60 gets you six characters at most, along with an extra costume for each of the characters in the premium pack you chose. So if that $30 of in-game cash isn't enough to net you at least a few more characters, it seems really expensive to me.
