Wow, a lot of mine were taken (particularly the adaptation and "that's not a real game" bits). I'm kind of in between on adaptations. I prefer an adaptation to explore at least the same sorts of ideas as the source material, but the details shouldn't matter as much.
The idea that games are meant primarily for fun I think is a bit dated. So, I get a bit frustrated when someone says something to the effect of "game x is not fun, therefore it is a bad game." That fun should supersede any other quality in a game and that a game should mostly be judged by whether it was fun or not doesn't work for a lot of great games. Spec Ops: The Line, The Walking Dead, and Gone Home were not particularly "fun" to play as far as I was concerned, but they were all very interesting. There is something else in all of those games that fueled my desire to continue (intriguing premise, twist on commonly accepted aspects of a genre, the desire to care for Clementine). I think fun is one way to engage and encourage the player to continue to explore the story, but it is not the only/most important way.
I suppose there's a strange mix of fun and other driving forces with many survival horror games. I dreaded every encounter in Silent Hill 2, but the aesthetic, atmosphere, and dream-like quality of the conversations kept me glued to the controller to find out what the heck was going on.
