I've not yet played each and every angle to it, including online or the scenarios, but with about 30 hours into a campaign with much trial and error learning, I am absolutely loving it.

The upgrades are numerous, including to generals, and special agents with various skill trees! Naval combat is also new, and if you want to be wealthy and advance your provinces, you've got to maintain a force on the sea.

If you love strategy and games where you've actually got to think for a change, missing this is a big mistake!
