World of Ether can be considered as a cross between the successful game, Pokémon and eBay. Players buy monsters from other players, fight with them to increase their abilities to raise rarer monsters, and auction those rare monsters to other players on the open market. When you level up in World of Ether you gain access to new and stronger types of monsters. The goal is to reach the final level, where you can get the rarest monsters and items to sell to other players.
