I want the base requirements of the game to be friendly with windows. This, unfortuantely, still has the most reach in compatibility because GuhNU/Loonix users will always have compatibility layers (which we will test)
If we want to go even less intensive and just do a top-down perspective, RTS or something less demanding as a starter project; this would also be acceptable. I also love level-building engines. The advantage of going for low-tech as far as display is ability to include mobile users. If we gain a vector to package a message to zoomers and younger. Cool.
