Myst is not the example you think it is. It's a fully 3D world with moving parts like the library staircase or the redwoods or the train section.
That they managed to pull it off for home computers in 1993 is nothing short of a performance focused mindset which led them to static images and QuickTime overlays. As soon as they had the ability, they released realMyst which was a realtime 3D version of the original, followed by realMyst Masterpiece in the last 5-10 years.
For that matter, Minecraft may be poorly optimized (it is) but without the effort spent on the chunking system that renders 16x16x(128/256) blocks as a single mesh, it wouldn't run at all. There's plenty of low hanging fruit (which may be more difficult to retrofit into the existing engine, or in the JVM itself) that other games have found and utilized, but without that initial performance optimization Minecraft wouldn't run at all.
