while your math seems accurate, also note this game recquires less cards = has less cards = less money recquired to have a descent amount of cards.
also, you are never recquired to pay a cent, and can get most cards that way, and can get free payed currency, though slowly @urquwno
@epeefencer if the cards you are refering to are "set-up blow" and "set-up throw", in my experience it seems that, instead of bonus to weapon attacks, like they claim, they seem to give bonus to other mele and range cards, respectively.
also, the impossible badge be would be just plain rediculous unless you payed. and making a badge you have to pay for is a bit to much. overall, i think the only time this game should get achievments is if they wee linked to a special room created by the games creator.
