TES has a special place in my heart. I've been playing the games since I got my first PC at 16, starting with Daggerfall, and my wife and I have bonded over Skyrim immensely. It's one of a few games we both put hundreds of hours into, and early in our relationship, before she started playing games in earnest, she was as hype as I was on the collector's edition I had picked up at the midnight release.
I can't say I'm happy about B's recent releases in the realm of the same types of games, but nothing is ever going to take away the time spent playing, discovering, replaying, and discovering something new each time. I just love the worlds they create. I will never stop seeking out the Dark Brotherhood. Their quests are the best.
MK9 and Saint's Row: The Third are my only selections not to make this list, and if you didn't put SR3 up there, I'm sure Johnny Gat has words for you (it was the first game in the series I played, and I absolutely love it). If you haven't played SR3 yet, take advantage of the re-release and get the OG on the cheap. It's a ton of fun.
EDIT: Eff it, I'm reinstalling SR3 so I can play it again after I finally finish AC: Odyssey.
