The fact that they won't sell the season pass at $12 but will sell you the base game + season pass for $22 is just a poke in the eye to those of us who bought the game on release. If I want the season pass content I have to pay $23 (sales prices the past few months). It was literally $1 cheaper to rebuy the base game during the summer sales.Without the Green Planet expansion the end game is kinda... iffy.
It is, however, a game that has been patched significantly since launch and makes WAY more sense now than it did at launch, as well as being a bit less punishing.
Still, if this is just the base game you'll be seeing a lot of red.
