Also about the Terraria Anime, Terraria has everything a fantasy/modern/futuristic rpg-like anime needs. The main characters are the Devs, the townsfolk (NPCs) are all support characters, and we have the bosses, the weapons, and the biomes for awesome storyline materiel. The Lunatic Cultist, Pillars, and Moonlord are the epic series finale.
