Some online stores are giving away beta keys with a pre-order.
Thats just another way to get ya.
I do think that the 3 game idea is somewhat of a good one if they are each like $20 so in total your only paying $60 or if they just bundle them into a "Battle chest" and you pay like $70-$80
yea..i think a 'Battle Chest' for about 70 or 80 bucks is acceptable but i think it'll be more like what 'Loop' is saying....that they'll probably charge 50$ each for each campaign knowing as we do that its mostly about the money.
