What are some games, preferably RPG's, where it starts out with a swords and sorcery medieval setting, but it has elements of sci-fi or aliens throw in? Maybe as a plot-twist or something gradually revealed as the game goes on. Something like;
<"This magical bullshit was actually alien techno-bullshit!"
The only examples I can think of are some of the Might and Magic games, and Ultima I with its space ships moments.
