Somehow I find those high-class wads to be tedious and frustrating. But I find slaughterwads to be a great way to clear my head and truly escape the normal world. They get your heart racing. No time to stop for a breath. If you even turn around, you'll be dead. They're all I play on Doom. Some of my favorites are Dholes and Royale Arena - Cannonball which have beautiful architecture and some puzzle elements but still swarms of monsters. Working through Oreo Cake Massacre at the moment which is more crude.
