A bunch of d20-derived games are, including C&C and Mutants & Masterminds.
My own "AssassinX" is OGL also.
Lalato said:I noticed quite a few people saying that if 4e isn't OGL, they wouldn't buy it... I'm one of the few ENWorlders that is not a DM or RPG Collector so I'm intrigued by this idea. Other than d20, are there any systems that have an OGL component?
Well, there is a difference between d20 System and d20-based (anybody in this hobby can tell the differences between D&D and Palladium Fantasy with their eyes closed ), just as there is a difference between d6 System and d6-based rules.Glyfair said:Always a difficult discussion because a lot of terms are used in multiple ways. D&D 3E is often referred to as the d20 system, for example. However, a game isn't technically a d20 game unless it uses the d20 license. Several games use the "d20 system" without the "d20 license" because they go through the OGL (Arcana Unearthed for example).
Action! System had a draft of their open source license, but was convinced that the OGL is just the generic content license they need. The only thing they released is their own A!S trademark license.Glyfair said:I do know Runequest, for example has a "Logo License" and SRD and uses the WotC OGL, but I believe other systems out there have their own variation of the OGL.
