If it wasn’t for a damn cold a few days before, I would have actually been on time with this GOTY list. For my #1 game, it’s a master class of improving a game that was already excellent to begin with.
XCOM Enemy Unknown is the closest a modern game has gotten to being the perfect game for me. The main reason was with the addition of the Enemy Within expansion that just made everything better. XCOM 2 was another amazing title; this time with Firaxis having complete freedom to grow it. Now with War of the Chosen, XCOM 2 gets even closer to perfection than the first game.
