Terraria is a game that is supported on Outplayed, tModLoader is just Terraria, but you can add mods into the main base game to make it more fun or just have more content, it would be a shame not have this but the main base game only (tModLoader can only be downloaded when you buy Terraria, since it is Terraria DLC, it is free and it allows you to mod the game with community made mods, just if you want to play the mods, you have to play it on tModLoader, not Terraria, hope this makes everyone understand why adding tModLoader to the supported game tab would be usefull, since it lets people record modded Terraria)
