>>2853429Most games with steam workshop I guess, or those listed on nexusmods. Friday Night Funkin', rpgs where you can import custom portraits, Darkest Dungeon, games with pixel graphics I suppose.
Apparently Valheim lets you import character models. Lumi and Inis used this to play with their vtubing avatars.
Making the modded assets is another thing, especially if it's 3d models and such.
