3.) Map Editor. The game includes a program that allows you to create custom levels, maps, scenarios or other materials for use in connection with the game (the "Map Editor"). The following terms are specific to the Map Editor:
A. Map Content: You understand that the content required to create or modify Starcraft II modified maps (as defined below) is included in the Starcraft II game client, and that all such content is owned by Blizzard and governed by this agreement. YOU ACKNOWLEDGE AND AGREE THAT ALL MAPS, LEVELS AND OTHER CONTENT CREATED OR MODIFIED USING THE MAP EDITOR (COLLECTIVELY, "MODIFIED MAPS") ARE AND SHALL REMAIN THE SOLE AND EXCLUSIVE PROPERTY OF BLIZZARD. WITHOUT LIMITING THE FOREGOING, YOU HERE BY ASSIGN TO BLIZZARD ALL OF YOUR RIGHTS, TITLE AND INTEREST IN AND TO ALL MODIFIED MAPS, AND AGREE THAT YOU WILL EXECUTE FUTURE ASSIGNMENTS PROMPTLY UPON RECEIVING SUCH A REQUEST FROM BLIZZARD.
I mean seriously... its not a request if you are required to make future versions of a map at Blizzard's request. Basically we are all agreeing to be Blizzard's map making slaves... and they get to keep all of our creative work. At least that is what I'm reading from this. Oh yea there is a B part too but it's not as outlandish, basically though if you wanted to make racist or hateful maps or put unlawful stuff in them then you should read B before you do but otherwise A should cover you. Anyway, this makes me even less likely to want to make maps on Starcraft II I might just stick with Stacraft 1 and finish up some old projects.
None.
