FTG writes- For those of you that have picked up XCOM: Enemy Unknown, you may have realized that the game is quite hard and very unforgiving. A mistake as small as positioning your troops wrong or forgetting to put your unit on overwatch can cost you the mission, or even the game. On my first try of XCOM, I barely lased three months before my best soldiers were brutally slaughtered by Chryssalids and a handful of countries decided to withdraw support.
The non-combat portion takes some trial and error but I'm liking the complexity of it a lot.
Great game so far.
As for advice, i'd just say that this game hates you and wants you to fail. If you remember that, you should do ok.
