It'll take you a couple dozen hours to finish up the story, but you can return to any map you want once the mission is complete--and you'll definitely want to.

GrimGrimoire is a fun and terrific gem waiting to be discovered. It may not be the most fully featured strategy game, but it's brimming with magical wonder and is easily recommendable.
