I want to write a computer game whose client is web-based–that is, you install the client software on your website and play that way, competing or collaborating with other players who are listed by domain name. (Xorph.com versus example.com GO!) (Actually maybe your opponent can be any domain that doesn’t have the game installed! Hmm.) Obviously this would be open-source, and cheating would be prevented by having some master server somewhere that keeps track of the numbers.
As exciting as this is, though, I can’t think of any particular advantages it has over the standard all-in-one web game model, where you sign up for an account on the master server directly and don’t have to install anything. You can even change the skin of most webgames yourself by installing a custom stylesheet in your browser. Can you think of advantages? Do those advantages lead to interesting ideas about what the game could actually be?
