you've been missing out on many years of good gaming then.
i have probably 90 games through various distributors( Steam, GOG, Epic, etc) and i play zero of them online.
have probably only connected for any type of multiplayer 5-6 times with any of them over 10 years or so.
i've tried some of the MMOs like Aion, Elder Scrolls Online, WoW 60 days
, Final Fantasy 14, The Old Republic, and a few others and have never gotten more than a couple hours into any of them.
i do not enjoy online gaming with idiots running around ruining my game experience and immersion into the stories.
but this does not stop me from playing a lot of the newer titles in offline modes and still having a great time with them.
