It was released under GPLv3 for all works.
I don't think the wikipedia article writers ever consider Open source game that people make Engine only and game made by others. And distribute sepeartely. There isn't original game here, no rules from Wikipedia apply as the article do not stand for explaining springrts under linux.
see description on Wikipedia:
Mod or modification is a term generally applied to personal computer games (PC games), especially first-person shooters, role-playing games and real-time strategy games. Mods are made by the general public or a developer, and can be entirely new games in themselves, but mods are not standalone software and require the user to have the original release in order to run.
for example the windows release of Gundam RTS isn't a mod, because it includes the spring engine
I have just compiled it and updated the wiki once more (the development of the needed dependencies requires maintaining of the wiki quite often).
Someone more knowledgeable than me in linux should take care of this as I am not sure I have written the scons instructions correctly (what is the scons equivalent of make install??)
Still, this is a great project, not quite sure you can call it a game, but great indeed.
The code compiles fine on linux, so it doesn't matter on what OS it has been developed on.
The compiling is not trivial, you have to compile a number of dependencies as well. I have been updating myself the wiki on that matter just a few months ago.
In definitive, there are still linux players and maintainers to an extent.
No activity on Linux, linux maintainers&players?
Upon the time, I have to say: it should be up to the authors to decide wether its mod or game. Total Conversion is another matter though.
I was very active in Zero-K, and blow those called ZK a mod. And submit 2 times in Springlobby bug tracker to ask for the "mod" change to "game".
As spring is engine only, and Conflict Terra, Kernel Panic, Spring 1944, Gundam RTS have no relationship with original Total Annihlation. They should not get tags of "mod" or "total conversion".
For those complain about engine / game seperate. Do you conplain about GTK seperate from GIMP？
