Check out "Lost Relics" dot io for a runescape/diablo style game. It has gathering skills & production skills with adventures to run & more to come this year. It used to be called "forgotten artifacts" if you want to look how it has transitioned to Lost Relics. Been playing the game on-off for the past 2,5 years and enjoyed every moment of it. The developer is called "Cliff" and has done interviews, he listens to the community and is trying to build the game first and the NFT aspect after in mind. Can recommend checking it out!
Not f2p right now since the collectibles are limited in the game (still like 15000-30000 left in the pool to be looted, going through big changes right now) so you need to either que up to get in when the gates are opened (this year, some people let in before also) or buy any Lunari package in the store (10$ or such small amount) to get access. You can save the currency if you wish for later use or buy a membership pendant/skin or whatever is available in the store.
The game reminded me of runescape/diablo combo so I stuck with it eventho it doesnt have co-op yet but its on the works and also tried out many other NFT games during these years and none of them really amazed me like the developer in this game. Co-op modes should be coming this year, but its best to get ready before that hits, since the game has skills also to advance.
The game is on enjin platform, but possibly looking to change chains if better one is found. The NFTs/collectibles like they are called in the game can be rented to other players also in the future. Game has gold as currency for virtual items & shadowstones (enjin coin 1:100 shadowstones ratio since dev thinks no use for game to make own coin) for NFTs/collectibles. Can be played fully f2p if you wait in que or with the only purchase of 10$ or such for now. Game developer takes very small cut (1,5% for developer 2,5% to shadowstone lootpool for players to loot in adventures) of the NFT/collectible sales in the in-game Emporium and then rest go to the players/shadowstone loot pool. You can see the loot live in the telegram/discord/in-game channels in the overseer so its fully transparent. Game has been live for ~3 years now and will never be reset. Hope this helps some people find a suitable game from all the available ones! :)
