I loved Terror of the Deep, and personally I prefer games to be challenging like that, but no, I was actually referring to the latest XCOM (and not the ironman mode, just vanilla). I think that it provides a decent challenge that different kinds of players can appreciate (it's of course only hard enough provided you keep your soldiers alive instead of just sacrificing them like pawns all the time). It's not even remotely close to Dark Souls or anything, but you must be thinking strategically, even using the terrain, and also take into account the latest XCOM's pretty cruel RNG-risks. Easy for me is a game that just lets you get away with a click-fest approach and then all of the sudden you are level 70.
