Well if we spend money on all these crystals and then they dont work in next game its just a waste
We've actually in a way been gipped out of the last 2 games too. Giants are glorified extra characters now (and from what it seems, will be even more useless in TT) and Swappers after having a game dedicated to having special powers will only function as plain characters now.
Like, I wasn't really expecting Swap areas to return, but they could have had a few here or there in the game. Or like dual element gates or something.
