Have you considered adding a mentoring and tutoring program? A 1-on-1 paid program that guides you through the courses and gives general feedback on other projects? I’ve seen and mentored a lot of people here, I’ve seen that a personal approach works wonders for many, I think there’s a market for that.
Test this by creating a limited-time course that teaches students how to create a full game from scratch, just 1-on-1 video calls with a mentor guiding the student using a program so everyone gets to learn the same things.
You could start with a total of 30 students and 10 mentors. A farming simulator could work perfectly since it’s actually a somewhat simple game to create, but as features get added the process can get really complicated, this covers beginners, intermediates, and maybe even advanced students.
You could look for mentors here in the community.
