Mixed first impressions for me - I like the depth of well, everything, the combat and building aspects. However, the launcher with it's unsubtle demands to make yet another online account is distasteful, and the way it overwrites the in-game graphical settings with the default the launcher thinks up every time you launch it is inexcusable.
At least inexcusable insofar as it doesn't work at 2560x1600 - text is extremely blurry and it draws giant black boxes around or over the top of tooltips. So every time I launch it I have to go through the crap launcher and tell it, no I am not making an account, and then change the graphic settings to a resolution that works.
