I must say, the 100 $GHST is a real turn off for that price. I would rather pay that and obtain a realT token and receive weekly dividend instead.
Games like this I am guessing requires a lot of transactions in the future, if Aavegotchi is like "tamagotchi" in the future. This will really wreck if it is running under the current ETH blockchain with unreasonable high fees (if they do not want to wait for 2 hours with 0.25 USD transaction fee)
