What about playing for the bad side toady? I mean to play as a skeleton in the world where it’s not strange wearing armor and fighting people.
There is a nice number of missions and maps and meeting more and more enemies. They grow stronger as well. You can hit and beat them but you may use some spells or call friends, too. But that’s not everything. The period between fighting can be spent changing equipment buying mercenaries and preparing for the next round. The areas and enemies change through the time but the stereotype is present.
