I love the game, and was trying to think of a way to remove at least some of the dependence on the RNG finding of maps to help spur more interest.

Progression% would incorporate 100% with the caveat that all contracts must be completed before moving on to the next map. No more rushing to get Archmages and/or Dragons to beat all the castles and find all the artifacts -- actual siege battles with carefully constructed forces from the continent you're on (or from the previous).

Let me know what you think.
