I'm trying to get the C++11 reboot of Magog into a playable shape by ARRP 2012, and the project's aims are pretty much aligned with the current incubator plan. The game is GPL, and an usable and approachable UI definitely fits with the design ideal. The idea has been basically to do a pilot project to figure out what works with a continuous world map engine.
Unfortunately, progress has been very slow so far, and though the core map engine is reasonably solid, there's still very little actual game to speak of. I'll need to get somewhere with that before I can start soliciting useful feedback. Still, even if I'm stuck with my own stuff I can still give feedback on other projects.
