Cursed Lands is essentially not "Allods 3: Rebirth" that I was waiting for. In principle, everything is correct; it's a completely different game. There is some small connection, of course—I remember in Allods 2 there was a document mentioning Khadagan. But if you ignore this small detail, Cursed Lands is a completely different game in terms of plot.
On the box for Cursed Lands, it said: "from the creators of Allods." Which once again confirms its independence.
Anyway, one shouldn't judge Cursed Lands poorly. I was also waiting for Allods 3: "Rebirth," but the developers slipped in a different game, and I liked that one very much too.
