As long as we are talking about old games that are still the gold standard, how is it possible no one has recreated the giant-god-monster and city management game Black and White yet?! That game was fantastic, and its premise so solid. It seems ripe for replication in more contemporary engines.
It’s the perfect game type for VR as well. There have been a couple “you are a god” games already, but none of them are close to what black and white was.
