Lots of fun. This game motivates its player(s) to walk, or ride something like a bike or skateboard, by placing "pokestops" in special locations like parks or statues. Players can spin pokestops every few minutes and get rewards like berries or pokeballs that directly increase their Abilities to do things like catch pokemon in the wild, or attract them to where that player might already be. All this being said - you can still become a powerful player sitting on a couch - but with other methods.
