I would like to create a game, where ( like in Pokemon Go ) the game maps are generated from real world map data. I would like to know, how does the license apply to my project, but the 3rd point of Legal FAQ is a bit confusing to me.

"The license does not force you to distribute or make any data available. But if you do distribute or publicly use anything derived from it - a Derivative Database - then the derivative database must be available under the same licence as the OSM data"

I don't make changes to the data itself: I generate game maps from the OST data. Are these generated game maps considered as "Derivative Database"? How is it possible to avoid that? What if the server generates the game maps on the fly, and sends them to the players when they start the game?

Is it enough to just mention it the "Credits" section of the game, that the maps are generated from OpenStreetmap data ( © OpenStreetMap contributors )?

Hello, I'm no lawyer but the way I understand it, if you make changes to the data (curating, transforming, etc.) you should publish it as ODBl.

Actually this should not be a problem for you, a few links to download the game's map data from your website would be enough.

If you generate raster maps directly from OSM data, and publish this images to the users, this falls under the "Produced Works" category, which has different rules. Mainly attribution as you proposed.

Hope this helps. Regards.
