I´ve made a cool 3D-Shooter which use the .bsp map file from Quake2. I made it with the Quake2-Editor and a other one. When I sell the game must I pay any license or so?! Thx

Is there a lisence to us the .BSP format? I would guess not. However, if you made it with the Quake-2 editor, then the map is technically the intellectual property of ID, and you must at least email them and ask them if you may use the map.

Hope that helps.
