You may have lots of users and I wish you all the success, certainly looking at the Foursquare leaders in London either they are cheating or they go to a hell of a lot of places and check in everywhere. Also games and trip creating location services like SCVNGR and Gowalla seem to be picking up speed, so maybe you will have a market. However personally I will only checkin for the following reasons: [+] I want share a place I like such as a restaurant with friends and this is an easy way [+] there is some discount e.g. free coffee in a place I like and go frequently that I can build upto by using something like checkmate for iPhone I certainly do not have the time nor inclination to go around lots of different places and checkin for a game. And that maybe a problem for you if more people are like me because I like world of warcraft and used to play it quite regularly.
