This web serial, along with its sequel 20020: The Future of College Football (both by Jon Bois), explores forms of American football in the far future that are extremely different from today's football. (If you aren't particularly into sports in general or American football in particular, don't be put off—I know basically nothing about sports, but I had no trouble understanding the story and finding it entertaining). What I like most about the web serial is its depth. It was very clearly meticulously thought out and researched, including various interesting little tidbits of local history and geography. I get the sense that the world, and people's lives, contain so many stories and so many possibilities that it's inconceivable to comprehend even a thin slice of what's out there. Give it a read!
