FL used WotC OGL when designing their OGL for YZE instead of writing their own OGL from the get-go and in that they where referencing the YZE SRD, not any other SRD. FLs new OGL is their own so they have 100% control over it, so it doesn't matter what WotC does or doesn't do. Their new OGL will of course point to the YZE SRD, which appears to also be updated with some new things for people to use when they design their own YZE game.Sorry to bother with a stupid question, (at least a naive question ), although there is something I don't get there: which part of YZE SRD is referencing D&D SRD enforcing OGL license? I'm not a specialist of D&D, but I really don't see mechanisms from D20 system been used in Mutant Year Zero for instance.
Can anyone shed lights on my ignorance ?
