My thought precisely.Yes, absolutely worth it. More worth it than G&K was.
G&K was a big advance over vanilla Civ V (which had disappointed me.) Still, G&K was somewhat one-dimensional, heavily in favor of warmongering. I kept playing Civ IV (LoR mod) throughout.There are a couple of bad spots in this game, but it's still by far better than either G+K and Vanilla. It's well worth getting, and the new mechanics add a ton of awesomeness to it.
