Since 2012, 2015, and 2018, the games I have played the most, and come back to over and over again are (in the order they came out): XCOM - Enemy Unknown/Within, XCOM 2+Expanson, and BattleTech.
There are other games as well, but those ones I mentioned above are so far ahead all other games, that it would be a bit ridiculous to mention any more. XD
