Not entirely sure of the game yet - working on the engine first - but I do know it'll have outdoor terrain, as I for some reason enjoy working on that.
And yes - it will be cross platform. Using the fox gui toolkit for the editor (www.fox-toolkit.org
) [which actually has some problems getting to run under MacOSX, unless the OSX x11 server is installed], and SDL for graphics of the engine itself. When I eventually move to sound, I'm thinking OpenAL. License will be lgpl, when I actually put the right stuff in the source files, and make everything comply.
I'll organise some screenies of the editor and post them up tomorrow.
Thanks for the feedback!
