SotS II : The Lords of Winter was released last week in an appalling state.
Depending on your tolerance for sloppy releases, you'll either feel entirely robbed or now employed as a beta-tester.
At best the game is in early Beta stage. The forums of both devs (http://www.kerberos-productions.com/forums/viewtopic.php?f=37&t=22033) and publisher (http://forum.paradoxplaza.com/forum/showthread.php?567065-State-of-the-Game) are full of apologies and promises of future improvement.
While it is true Paradox and Kerberos are likely to support this game for a long time and eventually bring it to playable state, having looked myself at the state of the game, I would suggest you do not part with your $40 to buy this early Beta unless you are willing to wait months to have a playable game.
