Sci-Fi project: plot obstacles (Patreon)

Hey FreshMen! I have a question about Sci-Fi plot. We know that MC will crash-land on an unknown planet, and he and his crew will need to find a way out. About the conflicts, villains and dangers on this planet, what do you prefer:

A. A group of alien villains, remnants of an ancient and supposedly extinct civilization, who doesn’t want to be exposed.

B. A group of mercenary villains, who are also stuck on the planet, and want to steal MC’s ship to escape.

C. A single, resourceful and cunning villain, with lots of tech ressources and robots.

D. No villain at all, just problems related to survival and the environment.

E. A powerful corporation that used the MC as bait for greater ends.
