It would be cool if more hobbyist game developers started making retro FPS games in the style of Doom or Wolfenstein. It's only marginally more effort than making pixel art platformers, which is a wildly popular aesthetic these days, and I feel that the retro 3D aesthetic has a lot of untapped potential. The Vlambeer game Gun Godz is a good recent example, it's pretty much Wolf3D with a nice art style.
Also, these kind of games make it feasible to write a random level generator that actually makes okay levels (there are such generators for Doom), and allow users to create their own levels with custom art styles in a day or so.
