I already preordered my copy, I didn't know about the Powerup points thing though. At least this isn't one of those exclusive preorder only things, otherwise fans would be in an uproar. Still, I'm glad I preordered. ^_^
If you don't have a powerup card they have a free one. Signing up for it gets you an extra 500 points. For every dollar you spend on new you gain 10 points and for every dollar you spend on used you gain 20 points.
i've been waiting for a nice new turn-based strategy game, and this is perfect! i'm on a fixed income (disability) so i gotta wait til june 3 to pre-order. do they just give you a code list to unlock the extra pokes?
