What about Worldopo? I invested about $1K into that and played it for about 3 years.
It was a Tron themed real world real estate land harvesting and battling game mixed with an AR collection scheme where you could walk around your owned land and harvest spill over resources from your factories that you owned.
It was cool as F*** and it went out of business because of covid and because of the Ukraine/Russia conflict plus the pandemic.
