Making your game general

ITT we discuss how to collaboratively design our games.

As you know, OpenGameArt has banned me for complaining about them approving content stolen from games, in particular Blizzard's games.

Be careful, when downloading assets from them. For example https://opengameart.org/content/rpg-game-ui includes 3 items from Diablo 1; see https://www.spriters-resource.com/pc_computer/diablodiablohellfire/sheet/59437/

Another case is https://opengameart.org/content/town-nature-tilesets-4-seasons-2-daytimes
and other Vikings of Midgard items by MirceaKitsune, says "All tilesets are licensed under the Public Domain like the originals, which were created by Fenrir Lunaris.", yet at the referenced site (https://rpg.hamsterrepublic.com/ohrrpgce/Free_Backdrops ) it says "These are user-created backdrops/screens that are either in the public domain, or creative commons. They are all free to use in your game. If you are in doubt as to whether or not you need to credit the creator, it's best to get in touch with him/her." I.e. they are at least CC-BY, which is not public domain. Even more, the downloadable game's archive (at http://www.castleparadox.com/gamelist-display.php?game=768 ) says "this game is distributed under the terms of the GNU General Public License." I.e. not only it is not public domain, but you have to release all changes back under GPLv3. Same goes with the game files included with the ohrrpgce engine. So if you use it, Stallman's FSF will sue you into bankruptcy. They actually came even for some some unknown indie Android game, with a few downloads.

The full list of what I found is at:

but be careful, because they there are likely more stolen assets at OGA. RPGMaker sprites especially like to pop up in like ever third submission there.
