Not Alone: Exploration is an expansion that adds 10 new places to replace the original ones. They can supposedly be mixed and matched to create 1024 different planets, but if such a thing is unrealistic, the following options can at least be used:
Base Game (all 10 original)
Exploration 1-5 (keep 6-10 from base game)
Exploration 6-10 (keep 1-5 from base game)
Exploration All (use all new places)
Labyrinth Variant with Base 1-4 (Use Lair/Jungle/River/Beach from original, Labyrinth from expansion, and the labyrinth variant in the rules)
Labyrinth Variant with all Exploration cards
