This game graphically looks really nice, a bit too much since it does not run well. The gameplay could do with a bit more challenge or something more to do than just betting once till the next knight comes. Maybe a knight could tell a riddle or be more unclear about what they want and it's up to your expertise to figure out what weapon they are asking for.
