You can find a wide range of swords, pikes, bludgeons, bows, arbalets, and even guns. Weapons have different weight and do different damage. Weapons also have different quality which affects their price and effectiveness. The same thing is the case with armor. It ranges from clothes to plate armor.
Different armors have different weight and offer different protection.
Magic potions and saints are done very realistically too. Also, there's risk involved in the preparation of chemicals. All can be used with keyboard, but I highly recommend a mouse. When you're in the city or the game requires you to make a choice, a corresponding picture is displayed with text layed over it. When traveling, you control a little person who wanders through map which reminds that from Civilization - little mountains, rivers, cities, forests, etc.
