Hahaha... No one likes me :'( I do understand though :p There's too many awesome skinner but... I really love the work of Teddy, Danori and Halucid (no special order)
When I said "fantasy", I thought of something like Magicians, undead etc... What is generally present in RPGs game. The problem with the basic medieval theme is that a lot of people will do generics knight etc... and nothing original as you or I would like... You should really consider the posibility to add more fantasy into the medieval theme
Well, finally, Medieval/Dark Ages is a cool theme, but don't allow a lot of creativity, the representatives characters of the medieval era are: Knights, kings, princes, princess, queens, peasant, clerics, pope(?), blacksmith... I think you should allow the fantasy, it would allows a larger creativity
