The campaign is different and you now earn gold from completing campaign maps to buy booster packs instead of random card drops in the PS2 game. I haven’t gotten far enough but apparently there’s an EVO mechanic where you get some kind of fragments that allow you to alter cards in some fashion. Not sure how I feel about this because that would make the meta even wider. Not that it’d be that big a problem with such a small player base with no competitive spring board.
