/vr/ - Retro Games

Theoretically let's say I'm interested in making a mod similar to that of Megamna 8-Bit Death match, which is a mod focused on a particular game series I really like, would Doom be the best way to go for making it?
I was considering using Doom since there are so many resources for making new maps, weapons, character sprites, etc., but I was also curious of the Duke Nukem 3D modding scene in that regard.
I love Doom, but always liked the look and detail of the Build Engine games.
Would it be harder to make a game in that engine?
How would multiplayer focused mod work in that engine?
Also I have no experience in modding or anything, this is just a theoretical question as I am mildly interested.
