Out of these, Blizzard games (Warcraft, World of Warcrat, StarCraft, and Diablo). Final Fnatasy is another good one. I love the Witcher trilogy, Mass Effect series (Andromeda is coming out!), and BioShock trilogy as well.
I like Metal Gear's plots and themes but I do not actually play it though.
Most of the old school fighting games you had already mentioned but I don't follow up to and play the most recent and latest sequels and installments with exceptions briefly for Mortal Kombat, since I have played Mortal Kombat X. Not too big on 3D fighters, as for them I would rather watch someone good at them play then try to become good at them myself for some reason.
I had followed most old school first person shooters such as the Wolfenstein 3D, the original Doom games, and Duke Nukem 3D, and I haven't had the time to real keep up with the much more recent popular FPS game franchises such as COD games though. Have only played a few COD games at a friend's place but very briefly.
