Yep there’s a reason why I’m more inactive nowadays, as well as school work I just feel way less motivated to make art for others as I feel it just goes nowhere most of the time. The only success I’ve had collaborating has been with @ChimbroDaPro and @InvalidProject where something finished was actually made, Makecode Forums 3. There’s a good reason why I made the Remastering your games! 
topic, I was just tired of my art going to waste and wanted to make art that would make a game complete.
I’d actually like people to collaborate, just make sure that you work a small but dedicated team and don’t collab unless you have something that needs to be worked on my multiple people. Pretty much every successful game here was made by a single person so if you’re reading this it’s very possible to make a good game by yourself.
