I think it would be easy to have multiple planets to crash land on. These are my ideas so far. Based upon sagitarius_2k's idea.
Standard Planet- The standard planet
No Oxygen Planet- Would have to make oxygen generator (sagitarius_2k's idea.)
Water Planet- Lots of water type stuff. You might land on a rock and have to build out from there
Poison Planet- Toxic Fallout would be common but would usually be shorter, poisonous plants, food and animals
Dead Planet- No sun, no life. Just rock.
Hostile Planet- Everything there is hostile. From plants, to animals, to people.
Radioactive Planet- Areas outside of buildings would be deadly with rads.
Lava Planet- Always hot. 100+ degrees. You must build a cooler fast.
Mechanoid Planet- Most factions would consist of intelligent mechanoids. Maybe even mechanoid animals instead of living ones?
EMP Planet- No electronics can be used.
