Shame that a lot of the game is pretty difficult, but the writing is definitely something to be praised. You don't see that very often in games. The Last of Us is probably the most recent one.
I noticed that your list is mostly console games, with a few older PC games. Have you gotten into PC gaming recently? There are a lot of games that are definitely worth your time and there are a ton of resources that can help you find games if you're interested. Browser/Flash games are pretty great, too. I'd probably put a couple on my top 100 list.
Probably the opposite of Grim Fandango, in that the writing is utter garbage, but the game itself is quite fun.
