I would like to use FOSS as much as possible with the important exception of Stamina because I have learned touchtyping in this program and I don't know how to teach touchtyping if I decide to use any other program. My first game was GTA VC and in first half of 00's its engine has absolutely rocked every schoolmates' imagination at those times but I am not sure I would recommend this kind of knowledge bomb to a young person. Probably OSM might be not worse than GE, at least it is more open and easy to edit.
