My first review was a one-star review, because admittedly I did not understand properly how the game works. I developed my fighters too quickly to reach higher levels, without paying proper attention to enhancing their gear. I restarted playing about a month ago, and I have to say I'm totally thrilled. The game pace is very slow, in particular, if you are trying to stay ahead of your environment without spending real money. This is possible, provided you visit the game very frequently over the course of the day, and develop your buildings to produce as much credits as possible. It is necessary to think about what you would like to achieve next, and then pursue that goal and only that goal at any one time. If you like X-com, and like thinking a bit while playing a game for a long time, this definitely is for you.
Oh, and for all the boobs in the game, frankly, I pretty much prefer beautiful figures over drab military types and eggheads with fake German accents.
