There will be trial accounts but not early on into the game, potentially end of beta. Those accounts will however not just generate imaginary nfts, it'll consist of cheaply rented creatures and healers off of owners, sure they will not have great stats but people will be able to test the game properly that way and owners will be able to earn some passive income providing the assets.
We won't track time spent ingame itself but other various stats within the game so it won't differ much from time.
Awesome there that those free-to-play accounts will help generate passive income for true owners of the asset. This is really a gaming revolution.
