My FFX project is certainly a cautionary tale. It has some cool stuff, but it’s also probably got some pretty big bugs. It was as far I could get in febuilder without learning any asm.
If you haven’t read this guide yet, I think it’s a must read for you:
This is how pokemblem went. I realized after a few months that I needed asm and started learning it. Then a few months later with about 30 chapters in, I cut my losses and started over in a buildfile. It took weeks to catch back up but it was necessary for what I wanted my project to be.
You can make a unique project in febuilder, but the more adventurous your mechanics are, the more suited it is to a buildfile.
Best of luck with your project.
