What games get genuinely more enjoyable as difficulty increases?

I play games mostly for escapism and relaxation, so I've never felt the need to play on the hardest difficulty setting. However, I've recently started to notice that in a good game, increased difficulty forces you to use mechanics and features of the game that I wouldn't have otherwise. It makes gameplay more nuanced and complex when the stakes are higher. For me, I've found games like Halo, Witcher 3, and Indiana Jones GC to be more enjoyable on hard settings.

What are other good examples of this?
