Just a preliminary investigation of Wormux and Hedgewars (two of my favorites) shows that Hedgewars relies on QT and cmake rather than GTK and make, and Wormux requires the SDL_gfx library >= 2.0.13 - highest that I can see in the maemo environment is 1.2.x. Don't think the Wormux issue would be a showstopper, just need to find a newer version, but QT likely is for hedgewars. I don't have time to look at them further for a while, so I thought I'd post this in case anyone else is inspired to check them out.
