Nah, building will be fun. Bad time will be for those who will use that bridge:)

Modern DooMs are… strange. The legendary status of Doom is granted by Doom 1 and 2. And those games are very different from Doom 3-5.

Original gameplay is quite saved by GZDoom and similar projects. Add there something like BrutalDoom add-on and you’ll get the best from both worlds: old Doom gameplay and more modern graphics.
