Planescape : Torment, indeed. And Dark Savior (Saturn).

Culpa Innata

Seriously people, play this game!

Still Life, was done by the creators of Syberia. Dunno if it is the same writer, though.

That sounds like a very good idea.

This, totally. Although it has no dialogue or text boxes, its simple story is just about perfectly told through pictures and events. Plus it does a really neat "backwards narrative," where the events leading up to the games beginning are revealed as you progress, and at the same time reveal what you're really trying to accomplish.

Overall, that game is nothing short of amazing. Just a perfect little point and click gem.

I'm having a lot of fun with The Longest Journey at the moment.

Dear Esher is getting the HD treatment as a re-release...

Assasins Creed series was a lot of fun... and the story was intense once all the peices start fitting together... made me want to finish the game....

The Metal Gears are a must... and since thw HD collection is coming why not try them out, i dont think you can go wrong...

Deus Ex is another with a fun story line...

Grim Fandago
Beyond good and Evil
Psychonauts
Mass Effect
Neverwinter Nghts (1 was neat but 2 sucked me in bigtime)

Fallout's were damn good for there time....

Infamous 1and2 amazing story when you get the dead drops and dig into the stories... its up there as top of the world...

The Batman's, Arkham City and Asylum they will never be forgotten.... they were done just so perfect... and the game was as hard or as easy as you wanted it to be...

Shadows of Colossus... not a story but a fill in the blank.... highly emotional and amazingly deep without using words at all...

I Second Enslaved, again an amazing story, wonderful tear jerking story!

i heard L.A. Noire was good from many people but never had a chance to try it...

and i personally loved RedFaction: Guerrilla it was a nice change from the standard fair of run and gun games...

and if you wanna scare the crap out of yourself hitup the Penumbra collection its the most terrifying gameing exsperaince i ever had... and the story if you find it is bone chilling...

Bastion - Combination of good writing and phenomenal voice work. The way the story is presented will have you hooked if you give it a chance to work its way in.

The Neverhood: good writing, plus a great sound track.

First few Monkey Island games.

Sam and Max series has absolutely fantastic writing that is very clever and funny.

Many Final Fantasy games and other rpg's like that, Chrono Trigger, etc. usually have excellent writing.

I'm sure I'm forgetting a whole bunch.

Lost Odyssey. I've heard it isn't the most original JRPG story-wise, but even if it isn't, I'd say it has excellent writing. The dialogue throughout the main quest can be funny, sad, and occasionally cheesy, but the writing really shines in the dreams. They are all text, but there's a lot of emotion in them. I was close to tears with a few of them.

I'm fairly surprised that no one's mentioned The Witcher 1/2 yet.

The Phoenix Wright series will do right by you. I also recommend Snatcher if you got an old Genesis laying around...funny thing about Hideo Kojima's earlier works is that they are more fast paced and piecemeal, so they actually are easier to enjoy. It also helps that those early games were less based on action, so the shock of transition from dialogue to action and back again is less severe.

In the licensed games category, I really recommend picking up Star Trek: 25th Anniversary and Judgment Rites for the PC. They feel very much like episodes of the original series, but are fairly open in how the player may approach dialogue. Check them out on Youtube if you want to understand how it works before buying copies. Probably the best use of an licensed property I ever had the pleasure of playing. :)

Grand Historia is also a good bet. Available on the DS, it is an JRPG similar to Chrono Trigger in that it is deeply involved with time travel - even more so, due to having many dead-end points that show the consequences of your actions, before putting you at a safe point before undertaking them. The other great time-manipulation story for the platform would be Ghost Trick, which has the witty writing of Phoenix Wright, mixed in with physics puzzles to resolve the situations that the protagonist comes across.

So...




Bastion
Baldur's Gate II
Ghost Trick
Grand Historia
Planescape Torment
Phoenix Wright 1, 2, and 3
Snatcher
Star Trek: 25th Anniversary
Star Trek: Judgment Rites
Persona 3 & 4
Valkyrie Profile

I'm going to go with, Persona 4.

Not for the plot itself, but for all of the little interactions with the characters that feels genuine without being forced. The natural evolution from the Social Links, and even the aspect of the Shadows to the Persona themselves. It feels very well done and there have been quite a few times where I laughed and just got drawn in deeply.

i would say three games:

*Gabriel Knight series
*The Last Express
*Silent hill 2

Well, since you seem to like things on the weirder side, like P:T or Sanitarium, you may want to try (RPS has a nice series of articles on it, starting [url=http://www.rockpapershotgun.com/2008/04/10/butchering-pathologic-part-1-the-body/]here).

I've read that English translation of it is so sucky it almost ruins the game, though.
