This version has been specially developed for Vista so one would think but it is totally buggy! The units often do not find their way when on the card they tried to move with left-click anywhere. On the graphics one could also work, which are active trier server not always online but good that is now widescreen and co. are supported, and the die was cheap at Amazon.
All in all, they should fix the bugs, because they might have had long enough time for it, so I understand also as a RTS fan these reviews here all ..
Yes, otherwise Earth is of course a great scifi RTS, only this version seems to be buggy. With the normal XP version I had no such problems.
