Yes, Spore, 10 years ago. What a disappointment. My dream game is an infinite space exploration game I guess. I've been disappointed by games trying to do that many times. Spore was a big one.
No Man's Sky was also quite disappointing. Although it did become much better with time (and I probably DID put around 100 hours into it), it's still not what I dream of.
I'm not sure we'll ever be able to make an interesting game with infinite procedural creation. I hope so. They really need to combine procedural generation with a team of people spending years making unique individual things to find around that procedural generation.
Still, the vistas in No Man's Sky can be amazing.
