I'm the project owner of William's Adventures
There is some big mistakes.
First of all, what I call scenario isn't only plot but level design too, and artwork, and so on...
And the programming is at an reasonably advanced stage : of course I won't send a project proposal without any programming experience with the project.
The game will be an example of what can be by open-source developers and to prove the power of Java. And it will increase the number of games available under platforms such as Linux and MacOS.
So, don't worry, this game is not a bad usage of Java Games community resources.
9 persons are already working on this project.
I'm very dubious about calling the programming "easy" because of the library being used, especially when the library hasn't been written yet.
It's more easy to write a game with a game engine, than with only OpenGL. And the part of Gamma that WillAdv uses is already written.
