So, Storynexus.com, the people behind Echo Bazaar/Fallen London and a few other games, have uploaded a functionality to produce your own text based browser games. I'm currently building a bit with it, it seems quite interesting.
Coincidentally, if anyone has the time, it would be nice if anyone could have a look at Etherworld, my own little thing based on an old campain setting. There's nothing there yet, beyond character creation, but it would be nice if someone could check if that actually works.
