Id love to see very generic timeless type of games with less content but with the opportunity for the community to expand upon with maps/items/characters.
I would love to see a Trackmania clone. plain racing game with 4 button controls, fun physics, simple yet powerful level editor and a leaderboard.
EDIT: or a binding of isaac clone with potential for shit ton of items as i have just read somebody else mentioning it.
I have a Prusa MK4 and i really like it. Even though you would get better quality prints with the same amount of money else where, its just good enough for my needs. And i love having the peace of mind that the owner behind it really likes open source. I do not have the feeling that i get features stripped away from me or some other corpo bullshit ruining my day. Use it since 2.5 years (~5 prints/month) now never had to fix anything.
