I am seriously addicted to this game on the Xbox 360. My very first playthrough was a 5 hour marathon in which I got my ass BEAT and saw the "bad" ending. This was my very first XCOM experience though so I chalk up my asskicking to being a noob.
And now I'm reading how people actually reload saves if they get killed which I thought would completely remove the sense of danger and urgency. I've inadvertently been playing my own version of ironman mode (no resets or reloads EVER) which makes the game that much more fun to me with actual consequences for poorly-planned missions and bad decisions. Guess I should actually enable ironman mode since I play that way anyhow.
