Used to play NFS:MW 2005 a few months ago, completed it. I also play the higurashi daybreak on PPSSPP because I'm poor Dwarf fortress is in there too Once played Space Engine, waiting for trees to appear then I'll play it again
Very rarely play the 2 games Space M+A+X (HMMM) and inve$t on dos-box (yet again poor) I just generally play games where you can do a lot of stuff.
Apart from osu!, I'm also playing SoulWorker, Minecraft and Transformice (Usually out of boredom, I just find osu! much more fun, but this is highly subjective).
Used to play Geometry Dash a lot, but I stopped a while ago.
In general, if I have the free time, I'm sticking to osu!, except if there's someone from my irl friends who wants to play something else w/ me (saying 'if' because that's rare af, I think I'm starting to get ignored by them just because I don't want to play League again).
Although, if there are videos on YouTube that catch my eye, and I'm bored from osu!, I'd rather spend my time watching them instead of playing any of the listed games above.
