Sigh, you didn't even address half my points. However, i will respond to each of yours (I'm such a good guy

).
First though, I will agree to disagree with you opinions - and they are your opinions (as what I posted are mine). These are not facts.
- I was speaking within the realm of D&D and I think rolling against a DC is what invigorated our roleplaying. I can run a wonderful, interesting, and engaging adventure pretty much just that mechanic. Everything else is completely roleplaying & DM adjudication. Pure, simple, and oh so fun!
- The OGL was useful for a lot more than that, but regardless what you list seem like good things. Though good or bad was never the question.
- The issue was interesting and innovative, not good or bad. 4e was definitely interesting and innovative. I also think it was really good, it was just not a fit for a lot D&D's existing fans at the time. I actually think it would do much better now (both 13th age and PF2 have similar designs but with some tweaks). I still think a simplified 4e some other tweaks (and less to no lore changes) could be a huge success. Think Shadowdark 4e.
- I'll take your word for it. So not innovative, but possible interesting. So is it safe for me to assume the rest of the items I listed to meet the "interesting and innovative" requirement?
- While your analysis is not correct, I did say the implementation of it was poor so I generally agree with what your are sating here. However, the concept is interesting at least and possibly innovative as well.
