Gwendolyn, 1 month ago @greene Don't have it (yet), but I noticed that additional DLC is advertised on the base game, but not on the listing for the Archaeologist Edition, so I'm assuming it's the game with its DLC included. (After a little searching) I came across a page here that seems to confirm that. https://www.ggrecon.com/guides/outer-wilds-archaeologist-edition/
