== 4C System copyright ==

[[4C System]] has twice been removed because it is a 'copyright violation'. Please cite evidence that this is the case. The 4C System is readily supported by respected publishers and outside of this page I have never heard this allegation. --[[User:Sanglorian|Sanglorian]] 23:44, 17 September 2009 (PDT)
:Reed himself said it is a derivative of TSR's Marvel Superheroes Adventures Game system.  Derivatives of a writen document under copyright is a violation of that copyright.  Other retroclones had the WotC's OGL to alow them to make it.  No such animal here. --[[User:75.151.7.189|75.151.7.189]] 13:12, 11 October 2009 (PDT)
::Sorry for the late reply; I thought I had this page bookmarked so I didn't check for new messages. Game mechanics are not covered by copyright. Derivative game mechanics, provided they do not infringe on trademarks, trade dress or copyright, are perfectly legal. Because Reed rewrote the rules without copying any material directly, he has violated no laws.--[[User:Sanglorian|Sanglorian]] 07:21, 25 January 2010 (UTC)
