Completely free and open source, simpler UI for anyone to get into imo

Aimed for heavily modding support to be specific

There are other source ports which tend to:

• Be as close as how it was intended while fixing critical issues (Chocolate Doom)
• Modernize the framerate but keep the gameplay same and welcoming to new users (PrBoom Plus and its forks)
• Make as ugly as possible (Doomsday)
