I got really hooked on Armory and Machine, there is an A&M2 but I’ve never played it.
Its the kind of game that only has a mobile version, it rewards you for coming back to it like any bad mobile game, but there are no ads, nothing to buy, and I don’t think there is any data shared.
The premis is you are work on a machine, making it faster, better stronger, more automated, and more able to produce things. Things can be in turn, turned into items that let you travel and fight critters. The loot from the critters can be used to make your machine faster. Its all a vicious factorio-like loop, and show how fun these mobile mechanics can be when there is no company taking advantage of you.
