I apologize for the vague description.I am trying to remember a game I use to play on PC awhile ago. You could be a dwarf, knight, and other characters. Each character would allow you to be able to use only certain items. The knight could use a long sword where a dwarf couldn't. The only mission I remember is where you have to fight two giant iron/stone creatures. Before this fight you find a hammer that only the dwarf could use.
