Whenever a newly registered member from "cyberspace" talks about recently acquiring x10 I generally jump to conclusions that there is pirating going on, as well. So I too can commonly be guilty of assumption lol
However, to answer the main question, you can defiantly create medieval games in FPSCx9. More so like games like
Thief. There are items in The Game Creator store that contain swords, bows, oil bombs, battle axes and more. Personally though I would recommend buying one of the medieval packs. They are pretty good.
I have very little experience using x10, only played around with it a bit a few years ago. So I can't really say what would be possibly with it. All I know is FPSCx9 is actually more stable.
