Hello there :D
Here are a few of my suggestions. (And no Unity and Unreal will not be on here due to my #### P/C not being able to run it so I have not tested them for a LONG time -_-)
My preferred engine is Clickteam Fusion with the XLua Extension and DLL Extension (Most extensions are free, including this one). Its one of those drag-and-drop engines though there are extensions that add Lua, Python and I think C#. It's not all that good with 3D though and its expensive as #### (100$ for Standard. 400$ for Professional) Not including the exports (You need to buy those too). Personally, I quite like it. It's decently fast and quite customization though don't expect to make 'AAA' graphics.
There is also Construct(The first one), which is like Clickteam's Fusion but its free and it comes with Python as well. Plus, the source code has been released so if you don't like it, you can just mod it. By the way, Construct is not all that good with 3D either.
Ever heard of SCP-Containment Breach? Well, that is written in Blitz3D. Which is free and open source. Don't want 3D? BlitzMAX is pretty good. Though there are a ton of functions to learn, its programming is a lot of fun and can be used to make both 2D and 3D. Also I think its Multi-Platform so you could export to Windows, Mac and Linux.
And for Text based games. Use Batch Compiler. Easy and kinda cool, though it only supports Windows.
So there you have it. A few engines I would (at least) try out. Most of these engines are either free or have a free trial.

I hope the rest of your day is nice :D
