Spring RTS

This is Spring RTS, it is not directly a game, but a game engine, that has multiple sub-games in it, similar to Uebergame, but for RTS games.

I wonder how I could miss it in my link collection of open source games, since it seems to be one of the bigger ones, the problem is, that it is an engine, with multiple games made with it and only some are open source, others are proprietary and even many supposed open source ones are not really open source due to cc-by-nc assets or similar issues. Another issue is, many of those sub games have no or no proper own homepage, because the games are delivered within the engine, but some games also have external releases like for Steam or on their own homepage.

So if you want to know which Spring RTS games are open source I just link the Libregamewiki page: https://libregamewiki.org/Spring , since they are probably the best authority about which open source games are really open source.
