Would an open-source HTML5 web/mobile app cut-down version of EWR be of interest? I dunno, I'm playing with the idea of starting one. The main problem I had is that last time I tried to write one was for iOS and it was such a big project and its not a road I want to go down again if I'm doing it by myself. Its a BIG ass project to do.
One of the benefits I can see about doing an open-source one is that the Theme (UI) could be customizable, data could be customisable. Of course there are technical issues, such as the HTML5 local storage can only handle a limited amount of data something like 2MB or something equally small and that the code could be really buggy.
I dunno, its something to mull over I guess.
if you make a mobile version of this game, i will surely lose my job because it'll be all i do at work
