I've been waiting to do a vanilla belt only megabase for ages, but have been waiting for the 1.0 release since it'll likely span longer than a release cycle. I don't fancy having a line where map generation has changed after 1.0, or certain factories not working because recipe counts have changed, stuff like that.
On the roadmap, it says "Final game balancing", which I don't know if that means recipies or smaller things such as damage/speed.
If the majority of things are actually final, I may make a start today
