There's nothing to add here really. It's not revolution, it's maybe not even evolution, it's just a careful preservation of all the good things we used to know and remember in a long brilliant history of space turn-based 4X games, be it in graphics, in mechanics, in lore or in any other departments. Just buy this game immediately - and you'll forget as nightmares all the GalCiv3, Master-of-Orion-without-number and other recent misapprehensions and misunderstandings. We'll have here on GOG Lord of Rigel sooner or later, and also M.O.R.E. maybe, check'em out too. Please, play the good games only!
You may see how people here compare it to Morrowind. But if you are the TRUE die-hard old-school gamer, you'd better play Daggerfall instead - the first (I don't count the Arena), and still the best, Bethesda trial in Elder Scrolls open-world-do-what-you-want first-person RPG sector of Universe. Oblivion is pleasant to the eye, yes, it is. But it's all it can offer. No depth, no immersion, no thrill of discovery. But you should have heard already that Skyrim is even worse... So - if you like the visuals, you may try it. But don't wait anything more.
