What are some of the games with the best writing?

[Reasonable]

Graim Fandango - c'mon, best voice acting and dialogue ever
Day of the Tentacle - for the humour
Longest Journey - very solid, good writing with decent characterization
Deus Ex (considering that a lot of dialogue covered political and governing discussion I was amazed they managed to make it work at all)
Portal - there's not a lot of dialogue, but what dialogue there is is fantasic
System Shock 1 & 2 (Shodan basically, no opponent has ever taunted me better, though a certain 'lady' in Portal comes close)
Beyond Good & Evil - fantastic characters and great voice acting

Uncharted & HS for their cutscene dialogue and direction, the best around IMHO
