Gaming

Some genres are just better for procedural generation than others. Like, for a Diablo-like, or a musou game, level design doesn't actually matter all that much, so procedural generation is a great way to get more content.

There's also games with pseudo-procedural generation like Warframe. That is, the individual rooms are all hand-crafted, but the combination and connections of those rooms are procedural. Meaning that it's the best of both worlds.
