Lately a lot of people have been working too hard on thinking of video games as "art" which is rather silly.. Video games are toys & puzzles. There's usually a per-determined goal in mind compared to most conventional toys, but straying from the rails and toying around with things is really what makes a game memorable or highly lauded over the years.
As a person with many siblings, I find that (when watching) they must be equally entertained by my in-game antics & perspective as I am by the in-game goals. This what keeps people watching during Let's Plays and why Speed Runs are great forms of entertainment. Forget the developer's art, the fun is in toying around with the interactive medium they've presented. After all, that's what a "game" is.
During Dragon's Dogma, Yahtzee found great entertainment by the character models he could choose from and the multiplayer character trade. When playing Dark Arisen, I made the character model look like a little girl & enjoyed running around slicing up all of the villagers. I haven't played as much of the game's girth as most people (since most quests are unplayable without their NPCs), but I'm not sure if that matters. I also had fun breaking the environment and surviving things in unconventional ways. (finding ways to sprint through missions and exploit AI in silly ways was great fun too.)
Do I have anything positive to stay about the story? No, it was laughably cheesy. Is the Elder's Scolls-like questing environment great fun? No. Absolutely not. Is the combat great fun? Absolutely not. But I certainly enjoyed playing it.
I did not equally enjoy Call of Duty Black Ops. The game was largely on rails, the characters were too stiff, there's very little time to openly enjoy the game design during the story. But, a lot of people enjoy playing the multiplayer since they get a thrill out of making toys out of and entertaining themselves with the other players. Most of the time people talk about it, they have great fun with the mistakes they made in multiplayer or their flukes and funny triumphs that they had in some matches. All the entertainment came from treating the game like a toy (or a puzzle for those that like to be the best), and not their artistic impression of it.
Games are entertaining and fun. And they're full of things you can toy with and chat about.
