RPG Maker and learning game design

I have been making a game with Rpg maker MZ in my free time. It is a slow process, but it is coming along. With no background or experience with coding, I had attempted to jump into Unity a while ago, but quickly became overwhelmed and gave up. Rpg Maker has felt like a great onboarding for learning game design. The simplicity of making events, adding in sprites, sound effects, dialog and anything else you want is amazing. I've gone from googling how to do the simplest of things, and now have a full town with npcs, a dungeon with puzzles and a few quests, and usually able to figure out any problems on my own. It feels like my own little world. I even have a small discord that I post updates to and get suggestions/comments from friends and family.

I think when I am done with this demo, I may give Unity another shot. I feel like I have a much better understanding of how to think when designing a game. I know Unity is a much bigger step, but I feel like I can at least see the staircase now.

So I guess my question for you is, what other programs have been instrumental to your game design journey? Have you used Rpg Maker and what are your thoughts on it?
