Symphony of the Night

Also, if you enjoy Doom 1 and 2, I highly recommend seeking out Heretic and Strife. Heretic has amazing level design using the Doom engine to create places that feel like towns and medieval churches and stuff. And Strife somehow managed to make Doom into an interconnected world with a decent story.

I’m not big on Hexen - the respawning enemies and the lack of weapons (there’s only 4, technically 12 but you only have access to 4) bugged me.
