I'm not sure how you guys are giving Skyrim more than a 7, the combat in that game is piss poor and it's glitchy as fuck. I guess the mods make it decent, but that's like saying Warcraft 3 holds up today due to custom maps.
Last game I was playing before this was Dark Souls, which I'll give a rock solid 8.5; the hit boxes are occasionally taking the piss, but once you get used to the fact that the hit boxes are taking the piss it's a fucking great game with tremendous atmosphere brought about by a well synchronised feel between sound, visuals, and mechanics where you get told a story by interacting with the world rather than by getting knocked unconscious by fucking cut scenes.
For me, it's purely customization. Lots of it. Plus lots of freedom and good setting, layout, story, outside of maybe the main questline lol. It was ok. Not the best, but good enough to get it a 6 or 7 and easy extra points for character customization, manor customization, etc.
I could totally understand a 6 or 7 score. Personally, I enjoyed the game for the most part. Not perfect, but pretty good. But I'm an ES fan.
This might be another factor, I play story driven games (with shit/stiff combat, unlike Assassin's Creed: Black Flag or Witcher 3) like this on easy. RTS / Strategy games I crank up difficulty, but with games that are hack & slash / story driven I don't find enjoyment in pro-longed combat/battles. I feel like a few strikes from sword / gun to the face should kill just about any opponent. I also imagine if my character is as badass as he would have to be to finish the main story-line, if the combat/controls allowed it, I would be too damn good and elusive to get shot, stabbed, bit, or hit, so I don't mind not dying when enemies hit me. No enjoyment in hitting opponent with 100 of the same sword slice or motions - that gets old quick.
I also think Alpha Protocol is the most underrated RPG of all time, and one of the best stories, if not best story ever. My only complaint that I can recall from the entire thing was who the assassin turned out to be. The combat was pretty shit, but you play the game on easy and enjoy the story/dialogue/character development, it has repayable value.
RTS / Strategy
Sports games (NCAA, Madden, NBA 2K)
I'll crank difficulty.
