There are a plethora of issues with Sacred Citadel purchased Through steam on win7.
1 - can't get resolution above 1600x900. With such a low budget and simple project like sacred citadel one would expect high resolutions without issue.
2 - sometimes in co-op mode (private or public game) when entering town other players beside game host won't be able to enter town and enter last battle instance. host and players can not move effectively in the instance. The only workaround is to break group and locally enter town on your own. Game profile still saves both locally and in group play.
3 - very minor graphical glitches that don't warrant much work. The two above issues are sort of annoying.
4 - Also, in fullscreen mode I don't get mouse cursor to select friends to invite to my games. This is frankly annoying as well.
Dear Sacred fans, please bear this in mind when purchasing. I hope DS and Southend fix these issues ASAP.. especially the instancing bug entering town in groups.
OTHERWISE, This game is AWESOME.
