In my case i consider "must have":
Advanced solars: i would like the option to craft the ultimate solar helmet, and also the solars are nice.
Extra Bees: Those would give me a reason to get into beekeeping!
Logistics pipes (i think theyll add this one once its released).
Optionally:
Twilight forest: From what little ive played seems like a fun adventuring land.
What are yours?
