The Vilecore is a good example of an average wad from >20 years ago. History has typically filtered doom wads down to the classics, but it's worth having a comparison. That's not to say it's bad. It has its moments, and there are some areas that clearly show vision. Some of the simpler structural details actually aged better imo than many overly detailed maps from that era.

Remake in the works, apparently. Here's hoping for some more verticality.
