3. XCOM 2 - Any Level
What makes XCOM 2 such a tough game to master, is that many of the levels are very achievable to complete. Hell, for long stretches of the game you might think you're doing really well.
The problem lies in when your troops die permanently. When this happens, they can only be replaced by fresh conscripts. If this happens often enough, you will eventually get to a level that will be almost impossible to complete.
Enemies will be too powerful for your rookie soldiers, and new, powerful enemies will emerge from the fog of war to tear you a new one. At this point, you will realise your team will have to suffer more death and suffering to progress.
And even if you do complete the level, you may eventually fail the overall scenario of saving the world. When you realise you are doomed (and you will) there are two options. The first is save scumming, the art of saving at a key point, and upon death reloading that save until you get the result you want. The second option is to stop playing the game.
Choose the latter.
