When I first put this game in, I honestly didn't expect much. I thought it would be a stereotypical alien game with little green men and stuff like that. Not to mention that the whole turn base thing sorta scares me off. I got it because people were ranting endlessly about how it was so good. So I put the disc in and I was blown away by all of the possibilities this game holds for players. The aliens were original, unlike anything I had ever seen before. And the concept was fresh as well, because you aren't just shooting aliens all over the place, you have to monitor the alien activity around the world with satellites, manage research and engineering teams, and keep your soldiers well equipped to take on the invaders. There are many things you can do in between missions, such as using your team of scientists to dissect a dead alien so you can find out their strengths and weaknesses. You can have your engineering teams design new armor or weapons for your soldiers. You can scan the world for aliens using your satellite uplink facilities. It just amazes me how reactive this game is to your decisions. If you don't respond to alien activity or maintain your satellite coverage over a country, they will withdraw from the council of nations that fund the XCOM project. Panic levels will go down in countries that you help by purging them of aliens. You can sell other countries some of your technology to get additional funding. There are so many things that will keep you busy in XCOM. One bad part though, is that this game makes it seem like you are literally running the world. While this may seem like a good thing, it is not. If you dont help a country by sending troops to get rid of the aliens, they are completely helpless. The countries seemingly cannot do anything without XCOM's help. Regardless, this game is definitely worth the money and will keep you entertained for hours on end
