I've long thought that it would be nice to invest some resources in speeding up PS development, and since we're developing a game, why not using the principles of gamification to do it? I'll give the first example that comes to mind just to make it clear.
There could be an Architecture Faction. To become an architect a character might have to complete a quest that requires some study of the architectural styles of Yliakum. After that, one may be able to participate to the in-game contests announced by the Vigesimi (i.e. the development team) on the dashboard. The contest may ask for a new 3D object or a texture. The large part of the project can be organized out of the game (through the forum for example) if implementing it in-game is too much time-consuming, but the important thing is that winning the contest gives an in-game prize (experience, trias, faction points, ...). Increasing the level of architecture faction could give access to more difficult and rewarding contests. It is just a raw idea but you get the gist.
Maintaining a system like this will require some "manual" work from the dev team, but IMHO the effort needed to implement it would be very reasonable if we compare it to the benefits on the development process and on the joy of all future Yliakum architects :-) .
The main point is: how cool is gamification?
