I have 1300 hours spent in XCOM:EU/EW. How does this game compare? Note that I am completely heartless and do not give one iota about story, characters, feels, cutscenes, and all that nonsense. All I care about are core game mechanics and systems, and how well the game's tactical combat challenges the player.
The game is very breakable strategically. If you want a challenge you have to pace yourself unfortunately. I play the game without using orders for instance.
