Thank God they did not kept PRIDE alive, because ZuffaPride would be a huge insult to the original Pride FC.
Their ways of doing business are very very different in every aspect.
Pride was not perfect, sometimes they also did some stupid things like putting prowrestlers that could not even throw a proper legkick against pro fighters. And many of those fights were painfully boring to watch. But other than that, Pride was great. Dana/Zuffa would have absolutely ruined it. So in that sense, it is good that they simply killed it, because we can remember Pride as the Greatest org ever, and not like an org that used to be the greatest and then turned into garbage.
