I've even made little back stories for each soldier I put in missions.
For example the only survivor from the tutorial mission was horribly traumatized and shaken up from what happened, since he was close to the primary team. He now wears a helmet in a way to keep himself distant from any of his other team mates, as he can't take losing anyone he cares anymore.
He will start to open up later in the game. That is, if he survives.
That's the sad bastard who inevitably dies a horrible death.
Are you playing Ironman on your first playthrough? I don't know which difficulty to start with, I haven't played the original XCOM but I'm a big fan of SRPGs like Tactics Ogre, Fire Emblem, and Shadow Wars. I'm not sure exactly how much that experience will help me in this game, though.
Right now I'm leaning towards normal for the first playthrough but Ironman definitely sounds the most intriguing.
Yep, Classic Ironman. Still early days but it's been a blast so far. Game doesn't play around.
Ironman is also distinct from the difficulty setting. You can go Normal or even Easy and still use Ironman mode. It just gives you one save to work with. Classic + Ironman is an ideal combination because Classic is specifically designed to give you the most "true" experience, in what you start with, the way A.I behaves in the strategy layer, the hit points enemies get, etc, so having only one save on top of that just adds even further to every facet of the experience.
But if you just go with Normal I would definitely also go with Ironman.
