I never played WoW but I was super into the RTS games back in the day (I even remember some of the cheats after 20 years). MMOs were never my cup of tea which I blaim on my misanthropy lol.
I feel you here though. It is super hard to excited for things after so much time. There are some older games I might pick back up if I could but I don't think I would be all that willing to put a bunch of time into them.
