I feel obligated to recommend this game to anyone who enjoys Medieval themes, Sid Meier's Pirates, amazing combat, or just awesome games in general. Not to mention the developers are small time and really deserve support so they continue making amazing games and updates to this one.
The "demo" is actually the full game with a level cap and can be downloaded at the official site:

Anyway, check it out for yourselves. It's at least worth a try.
