I grew up playing the original XCOM - UFO Defence when I was very young (not any of the other garbage XCOM titles that came soon afterward). Though I completely sucked at it, I simply loved it because of it's dark, creepy atmosphere and wide array of options in managing my war against the alien invaders.I'm older now, and more accustomed to strategy-war games, and have just recently purchased XCOM - Enemy Unkown after reading so many great reviews, and hoping that it really would stay true to the formula of the orginal. The game arrived last night, and before I knew it, 6 hour had gone by.So far this game has FAR exceeded my expectations. Not only does it hold true to the orginal game, but it is loads of fun. The combat system is perfect with you now being able to utilize cover much more stragically, and having more combat options while on the field. The only thing this game lacks so far is the creepy atmosphere of the original, but that is just light nit-picking compared to all the greatness this game has to offer.The first few tasks at the beginning the game are very linear, but this is done simply to show you how to play the game. After that, you are on your own to build your base, make all of the engineering and research decisions, and decide on when to deploy your troops and how to deploy them. Your choices of where to set up your base are limited compared to the original, but this is easily overlooked. So is the fact that you can only have one base. One base may not sou.
