From the user's perspective, a RailsGame is a browsergame, so it's made of web pages. Once you get into the meat of the game -- the part that has a lot of two-way communicating between the browser and your server -- you'll want to leave one RailsGame-enabled page up instead of switching from one to another. It takes time to connect to the game server, and you're better off doing it once than doing it repeatedly.
