any freebuild owned by a higher id is a pretty good start
If you be their friend and all of that they will stay on Blockland more too which is great
Also I have 3 more projects after Randomizer:
Private project for someone (wont be hosted)
Reverie Fortwars (it will have a new name since it is being remade from scratch)
Boss Battles (maybe, the idea is to have bosses go into phases based on health, and of course bosses and classes will randomly switch each week so you are not always playing the same classes)
