This as been around for a long time, guys. Bethesda is not the first company to heavily modify something and call it new. That's existed for a long time. Hell, most things that companies call new are not new from scratch. That take the same basic foundations and tweak up from there. It can definitely be considered lying, or exaggerating, but it's been around for a while.
And I haven't found the Skyrim engine to be the pos everyone here says. My criticism's of Skyrim are mostly within content and other areas. I find the engine fine. In truth, the "crappy" physics make the game more awesome at times.
And every sandbox free-roam game has a lot of bugs compared to linear games.
