you mean the upgrade
the plus edition is what we always knew it would be, a smaller version of the game, playable while you have PS+, just like any other PS+ free game.
the upgrade is just something they introduced recently. and it's optional.
no they said from the start 6 months ago you would be able to upgrade to the full game for a discounted fee. well the discount is nothing to talk about and you dont get the full game, you get the ps+ version still which can expire.
The demo is nice, but they should not of made out it was going to be anything more than that.
