This looks interesting, only single player so far as it's still alpha.

Also apparently only works on the Steam version at the moment (I haven't tried so can't confirm)

Alas, I only have steam variant so can't test otherwise. :(

-_- not surprising in the slightest since, to this day, terraria modders remain obsessed with steam and ONLY steam.

can't use N Terraria or any number of other mods because they're all steam ONLY to the point where browsing the terraria forums for mods leaves me wondering if mods for this game are quite literally a steam exclusive feature of the game.

and that's if the modder(s) in question even know what gog.com is at all.

people certainly do LOVE their DRM, huh?
