Too many alien clocks
Playing XCOM 2: War of the Chosen and all these timers really annoy me. There seems to be clocks counting down or up everywhere in the game. I enjoy building my base and sneaking around shooting the aliens in the face. It is hard to focus on that when the game is like the inside of the clockwork mansion from Dishonored 2.
The Lost are fun to trick the the factions fight each other in the missions.
