You did not.
The game included Minetest (to point it out explicitly) and a lot of related mods, some of which are licensed under the GNU AGPL v3. Simply changing the license of the entire game (in terms of what you distribute) to the GNU LGPL v2.1 (which you did) does not solve the problem because the GNU AGPL v3 does not allow you to license the mods under the GNU LGPL v2.1.
CC licenses, which are used largely by the media content in MT and the mods you included, generally require attribution to the author, which you did not do. In addition, the CC-BY-SA licenses do not allow you to license the content under a different license, which you did by changing the license to the GNU LGPL v2.1.
You could make a bundle of Minetest and some mods. However, as far as I understand, you need to give proper attribution and address the license issues, such as by having different components under different liecnses (which most mods do anyway, with code and media under different licenses) and/or by asking the corresponding mod developer(s) for license exceptions. Other people could make such a bundle as well, provided that licensing issues (among other things) are properly addressed, and doing so properly is not considered “pirating” in terms of copyright violation.
