I'm not sure why you think i defend Bethesda... i wrote in my original message above that "The issue is that Bethesda doesn't fix their engine", which is also why i wrote that "in your own words > they won't invest properly in updating it for modern times" in my second message. My argument was really the part i originally quoted, specifically this:

> their insistence on sticking with their old creation engine

...because it is a common thing to say about Bethesda. But the reality is that they can stick with their engine just fine - they just need to fix their bugs. The problem isn't that they keep using their engine, everyone does (as you already wrote in the first paragraph here), the problem is that they do not give their programmers the necessary time to fix the issues with their engine.
