Fantasy Life isn't just about you being happy; you can also make other (virtual) people happy!
As you stroll around Reveria, you may see people with a thought bubble saying "..."over their head, meaning they've got a problem and only you can solve it for them. Cue Requests !
Speak to the troubled citizen and you'll be asked to do a task (a Request) in exchange for Dosh and an item. The task will vary, but generally involves slaying a certain number of monsters or giving the person a certain item(s).
It is completely at your discretion whether or not to accept the Request. The purpose of Requests is solely as a means to obtain Dosh and items (and a bit of experience). On occasions, you might not be able to complete the Request unless you're in a certain Life.
You can accept up to 30 Requests at a given time and you can review their progress by tapping the Quest icon on the bottom screen and navigating to "Other Requests".
Note : If necessary, you can also Give Up a Request you've undertaken by pressing the Y button when reviewing the Request. There is no penalty for declining a Request, so don't be afraid to.
