I find the hidden movment screen EXTREMLY annoying, i dont know exactly why, but its really uncomfortable for me, it takes me out of the exparience. I much rather have a bit of transparent text on the screen ( think "alien movement" in XCOM: EU) as an option.
Overall i enjoy the game, but for the long haul the hiddenmovement screen might be a game breaker for me.
And yes, i never played the original xcom, XCOM: EU introduced me to the franschise and i very much enjoyed it.
