I started with just bobs mods. Vanilla takes me 15-30 hours. Bobs it’s about 60. If you have never tried mods, and want to make the game a little bit more (and have already finished vanilla), bobs is an excellent start.
Next is Bob + angels. Combined this dials up the complexity, base size, and forces you to think a bit more. 120 hours to finish
Seablock - this takes the above and forces you to work with no space at all - very cool. But long. 300 hours.
Mods. The hours come from that.

Space exploration. 500 hours for this.
