I've played many many many more games than this, but these are the ones that really hit home for me. I don't own them all anymore, so the only games I'm actually playing right now are League of Legends on PC, but my friend I played it with just passed away so I dont play it as much anymore, and All the games I listed on the PS4. Except Arkham Knight anyway. It was a great game, I just dont have time for it between the other four games I have on it. I did have The Witcher III, but it didn't really interest me. I'll probably go back and play it somewhere down the road, but like I said, between Bloodborne, Dark Souls II, MKX, and now Fallout 4, there just simply wasn't enough time for it. Plus by the time I'm done with all these, hopefully Dark Souls III and Uncharted 4 will be out and ready to play. Favorite Game series of all time is definitely the LoZ games and the Souls series including BB.
Out of Zelda, my favorites are probably Majora's Mask and Skyward Sword, but I also obviously love Ocarina of Time and Twilight Princess too.
And out of the Souls Series I have to go with Demon's Souls. I put about 1500 hours into Dark Souls total, so I played that more than any other, but I still put about 1000 hours into Demon's Souls. I just think the level design in Demon's Souls was more imaginative and despairing. Not to mention the Valley of Defilement was so damned depressing at the end. One of the few games where I actually wanted my character to die in the end lol.
Sorry for nerding out. I don't do it that often lol. Much needed!
