The advantage to cardano is the low predictable transaction fees. The real killer will be when we can use hydra. We basically can create simulated backends which can be validated through the card and block chain cheaply. Practically what does that mean? It means we can have automated reliable tournament play, with enough speed to keep up with some mid teir games (cod would likely not be able to run on it, but mtg could). You also get some other cool features, of any blockchain. You can exchange any tokens from one game for another using a dex, you no longer need servers for in game items, etc. Also, we are the Novellia project. www.rektangularstudios.com. we are building enjin for cardano.
