I am relearning C2 after a few years away.
I have tried rpg maker but you are limited to rpg games.
There are a few game making software programs on steam but they all have their limitations.
My 11year old can solve many of my game making questions.
It looks like I will be settling down here as this doesn't seem too difficult as soon as I figure out where things are. Also, if you plan to publish your games, this seems to be the place to do it.
As for learning slowly, I can understand that. C2 has a benefit that they don't mention. It will help you keep your mind sharp even after you retire.
Did I forget to mention that I am also a bit slow at things at 75? I just never grew up.
You can try those other engines, but I will almost bet you will come back here later. I did.
