I have partially written a web-based Ultima-style tile game that runs completely on a web page using PHP.
It has an entire backend server that controls the world, and I don't leave
it running, so not much happens, but you can see the GUI and graphics I
had in mind. Log in with username/password of 'guest:guest' to try it
out. I don't think you can move either because my goal was to make the
characters autonomous, so you would only play a "coaching" role. My,
that sounds inviting, doesn't it! Someday I will continue this project,
perhaps when I retire in 2025...
