Something like that. I'm thinking a few basic resources, such as food, wood and stone. On the map there'd be a tree, pond and quarry. Then you can mine a bit, and then buy houses and hire people to cut, fish and quarry.

As for the jumping, I was thinking you'd kill bad guys by jumping on their head mario style. And that would give you some other resource, such as coins.

Interesting. switches that do stuff when you jump on them and you have to repeatedly jump on them?
