is there a list of game engines that are NOT sdks or require programming knowledge?
What would you do with a game engine without programming for it?
There are a few "game creation tools", but they don't really give you the possibility to create something actually new without programming.
You might be more interesting in modding an existing game.
There is http://t3dgm.thegamecreators.com/.
You are very limited with these sorts of "no coding" solutions, but if you're dead set against learning at least some form of simple scripting, then this is one of the more popular options. I've never used it, so can't vouch for it directly.
If you are at least willing to learn a scripting language at a minimum, then your options expand greatly, as many of the more popular game engines out there have some sort of scripting option that will expose many if not all of their capabilities without you needing to learn C++.
If I were you, I'd use my time learning C, C# or C++. Trust me, they're alot more useful and versatile.
