So I noticed that the game itself sells for $14.99, but for some reason they have a "Mega Pack" for $10.79 that includes the following:
• Don't Starve: Console Edition
• Don't Starve: Shipwrecked Console Edition (DLC)
• Don't Starve: Reign of Giants Console Edition (DLC)
• Don't Starve Together: Console Edition
• PLUS Don't Starve Shipwrecked and Autumn PS4 Themes!
It's cheaper to buy the bundle with the DLC!
I'm not sure if this is a pricing error, but it's definitely worth it if you are looking to purchase the new Don't Starve Together. See below for the stand-alone title for reference:
edit: OK, so evidently (per the PlayStation Store on PS4), it's 60% off for the Mega Pack if you already own Don't Starve: Console Edition. It's nice that they gave people a break who already owned the previous content while also throwing in a couple themes (and DLC if you didn't already have them!).
