For example: gcc as de facto compiler and libsdl as cross-platform render/sound/input layer.
Personally, I dislike SDL.
Are there any plans for replacement with functionality of discarded code or all we'll have are ugly similar colored and paint bucketed actors?
Of course, the code will be updated and so will be the quality. But, we will need artists, many artists.
This is not a problem, I can add even skinned-animation meshes or whatever you like, with any quality you like. But I am neither 3d artist nor 2d artist so I cannot create content. This will be up to the community.
Also there are detected some work on D3D10 render which IMHO don't required for project with such engine. This render not only non-cross-platformed, but also requires Windows Vista/7 when there are many windows users which still using XP. So, the question is "why D3D10"?
Should you have looked more carefully, there is D3D10/OpenGL render. So technically yes, you could run that on linux with some preparations. Sadly, I never programmed for linux/mac so I can nither do basics (create window in linux, work with files, etc) nor I know what libs, compiler options etc are required.
D3D10 doesn't require Vista or 7, ran on XP for me.
It ran because I did not find D3D10 and was switching to D3D3.
