It's a light ARPG where you can freely swap from a variety of jobs that determine what skills and abilities you have. Unlike most other games in the genre, Fantasy Life has a substantial focus on skills beyond combat. There are basically three different classifications for jobs: gatherers, who have abilities suited to gathering specific types of materials, producers, who use those materials for crafting goods, tools, and weapons, and combat classes. All classes can fight, but combat classes specialize in fighting at the cost of being largely useless for everything else. It's a very fun and rewarding loop to develop all of the jobs so you can maximize what things you can do, but it's also completely valid to beat the entire game playing as any job. I beat the game as an angler/fisherman just to see that it could be done.
