I'm having a very rewarding experience doing this mostly from scratch in Gamemaker using Claude.

When I see apps like this, I get the fear that it has those RPG maker vibes where all the games will be same-y. That Roblox / minecraft kind of lack of uniqueness that makes for a great mod-game, but it always harkens back to the same patterns you use in the game engine that start to bother gamers like me.

I'm working on a pixel RPG in gamemaker right now, using Claude as help, and I've developed a reasonably complex classic pixel RPG in less than a few weeks. I still had to constantly correct claude, but it was more often 10 steps forward and one step back. My whole engine and experience is mostly done, and now it's the fun part of designing the world.

I almost have an entire sheet of custom sprites I plan on offering as well.

I wouldn't trade my experience for some out of the box thing where I don't own a lot of the game's core content.
