Glad you like the concept! Indeed, everything revolves around the crypto embedded into Townforge

There's basically there's two sides to the gameplay inspired by MC:
1) There's the Minecraftian-like hybrid of a voxel builder, which allows the creative freedom of "Creative mode" in MC (i.e. you can freely move in the world, you don't take fall damage etc), but with limitations due to the economy (instead of having to go down deep into mines to work with your pickaxe in "Survival mode", it's the in-game currency, player-driven markets and production mechanics that determine your available block types and quantity).
2) Couple this with survivalism (food, warmth, other upkeep) and RPG potential, and you've got a world revolving around the creations. We acknowledge that not every wants to create voxel-based 3D buildings, so it's also possible to play just the economical side of the game - or, you can hire an another player to work as your architect, export their creations as VOX files etc.

... naturally we don't try to reproduce "a crypto-MC", but leverage the parts that make our game unique and interesting while drawing inspiration from the gaming world. Having the game on a blockchain is challenging on some fronts (for example, no redstone circuitry or real-time physics), but makes other parts more intriguing (for example, there is an intricate economy revolving around the blocks).

We currently have a scripting language in the works that'll allow players to embark on quests; this scripting language allows old-school text-based adventures with flavor images, and all those quests are pushed into the chain in a custom scripting language. The rewards come from the Game account, so nothing is created out of thin air. We're hoping that this will allow us to create an immersive RPG side to the game and deepen the Norse-based lore peppered by our own creative freedom.
Some rather recent games with similar quest mechanics are e.g. the game series Sunless Seas & Sunless Skies.

We're focusing on this RPG-adventuring aspect at the moment as well as general game balance. Hopefully we'll soon have adventures to showcase!
