ESL (ESP Lite) is a newer file format for mods in the Creation Engine, the whole backend to the game basically. Fallouts 3, NV, 4, 76, and Starfield all run a very heavily modified Gamebryo engine (from back in the Elder Scrolls 3: Morrowind era, ~2001), which over time mutated into the Creation Engine. Previous types were ESM and ESP, and they were locked to a total of 254 individual mods. If you went over the game would most likely crash… speaking of, CTD is crash to desktop. Lastly, DLC is downloadable content, aka usually extra paid stuff to add into the game. That can be perceived as it being good extra content or bad in that the content should have been part of the main game all along.
In case you didn’t know, fallout went 1, 2, 3, New Vegas, 4, 76.
TTW summary:
Only way I managed to play FO3 and NV was by playing with TTW, to me the franchise ended at the second game…
ESL, CTD, DLC?
