It's Skyrim. With all of the DLC.
It's excellent, and you should buy it immediately if you haven't already.
It's also the PC version, so you can have the very best of times mucking about with some absolutely fantastic mods and marvelling at a game that somehow looks better than TESO...and plays immeasurably better too. If you're looking for a quintessential Elder Scrolls experience, accept no substitutes.
