I played the game for the first time a couple of days ago, put it on Classic/Ironman and buckled up. Came back from a couple of squad wipes, but eventually it all went to hell and it was over after 153 days.
Second attempt is going amazing. I'm a little bit beyond where I got to last time when my game ended and only 4 nations are out, I have satellite cover over everywhere else. My sniper is godlike, she reached colonel and has been racking up kills. I know people have touched on it before but to begin with, I had every intention of naming my troops. However, after a few missions it doesn't feel right. So, Melaina it is.
I finished last night with an utterly ridiculous terror mission. 4 Cyberdisks, 5 Chryssalids, 5 Floaters. There were several points where I thought it was going south, but I somehow pulled it back. I did lose one guy, he died a hero though. There was a Cyberdisk, a Drone and a Chryssalid lining up my guys, they were in close proximity to one another. Augustine - a heavy - could have moved to cover, but had he done that, it would have put several others in danger of dying. He had to sacrifice himself for the team. He lined up a rocket, fired, and it wiped out both the Chryssalid and Drone. The next turn he went down in a hail of bullets (lasers? lol), but it allowed me to move my other guys around for the kill, ending the mission.
To me, XCOM is the best game I've played for many, many years. I love it.
