Oasis: game idea
[A game where you spawn on a plot of land with a generator using the generator you get more items or the games currency then you use the currency to buy new stuff, upgrade generators, expand your plot, etc]
More information:
This would be an open world game where you can explore new areas in the hub (the hub can contain markets, new areas to get new generators or items, community generators with different types of currency to buy different types of items) then travel back to your plot of land (or island if you will) where you use the currency and items you bought to make new builds on your island with the more valuable materials you use the more your islands worth goes up
but like more developed with a more open world thing
