List of Moddable Games?

Goal:
To initially create a level or two for my LD portfolio using existing game assets (So that I don’t have to start from scratch: creating art assets, animations, mechanics, etc)
I will eventually create a level via Skyrim Creation Kit, a puzzle level via Portal, and a multiplayer level. But I’d like to start with a playable singleplayer level that isn’t an FPS. (besides Skyrim)

Question:
Does anyone know of a list of 3D moddable games besides Unreal Tournament, Elder Scrolls, Half Life, Left 4 Dead, Portal, or Gears of War? I can’t seem to find games that I can make levels for. (But please feel free to include FPS games, and 2D games for knowledge)

Thank you.

withj UE4?: ARK, SQUAD, the new Unreal Tournament. their mod assets are free available thru the epic launcher.

Are there more than those 3?

Not with UE4.

What about with other engines?

There are hundreds, the older the game, the more likely it is to have some kind of mod support - just go through your collection and do some googling.

Grand theft Auto in general is a moddable game.
