Sales

Do you allow us to sell games created with the Spring engine?

[Satirik]

argh did it with pure so yes but if you edit spring's code you'll have to provide the sources etc

By GPL any source code change for the engine, and, arguably, the LUA code you use is required to be released to the public.

By the same GPL, you can easily lisence your MODELS and ARTWORK with another license and sell those aspects of the game, which, in most cases, will be about 80% of your work put into the game.

So yes, commercial opensource projects are completely doable, although, rarely appreciated by the community they spawn from.

So, I can sell it, but the community won't like it, and I have to give credits?

the spring community would be happy to see a working commercial game using spring

Proved to be wrong in argh's case. But maybe they have learned something.
(neither of us are to say what the community will actually like/dislike, we can only speculate)

@ OP :

You should read the GPL license, I cannot give you clear answer on whether you need to credit the authors of the program or not, and if yes, in which way.

This implies, as others said, that your Lua and BOS scripts must be open source (GPL compatible license), but you can sell the artwork (models, textures, icons, cursors, sounds, music, etc.)

So basically you'd sell the artwork and give the Spring engine and your own custom code away for free.

if you edit spring's code you'll have to provide the sources etc

but you don't have to make them available for download on the internet

[Tobi]

Only if:
1) you don't make the package you sell available over internet either, or
2) you include a written offer valid for at least 3 years to get the source.

Elements of the community were happy, other elements were not.

Models, textures, sounds, music, icons, cursors, custom effect bitmaps and - potentially - maps, which consist of manually generated bitmaps.
