When one player can have a half-hour heartfelt father/daughter talk with the person playing his character's daughter, and make it damn convincing, then I will accept that NWN is as good as D&D* 
When you can interrogate a captured dark paladin using a half-orc fighter and an elven druid in the good cop/bad cop routine (me playing the half-orc, one of my best friends playing the druid, and the DM as the paladin), shortly after that half-orc fighter's epic-level sorceress aunt and the druid's epic-level mage of a wife engaged in a ritual spellcasting to move the moons and cause an eclipse of the sun to put the fear of god into an army of Pelorian worshippers being falsely driven to war by said dark paladins, with the result that siad sorceress and mage have been plased under a geas by Pelor himself to bring the dark paladins to justice as an atonement for interfering in the business of the gods, then NwN will get as good as DnD.
Likewise, when you can DM a campaign where one of the recurring bad guys is a vampiric sorceror who works for a red dragon the party are attempting to poison and kill, and never fights fair because he's always dissolving into his mist form and then reforming and attacking from alternate angles (not strictly kosher under the rules, but still HELLISHLY fun to do) then I will accept that computer-based RPGs can beat the pencil and paper kind. Sure, they're fun, but they just aren't as flexible, nor are they the same kind of social event.
Speaking of which, I've got a game of Shadowrun tonight. Our group is bodyguarding a Yakuza boss who's visiting New York from Japan. We have an elf raver with implant blades in her arms, a dwarf decker with an addiction to stimm-patches, another dwarf who has shotguns implanted into his bionic arms, loaded with EX-Explosive (anti-vehicle) rounds, a troll who can lift is own hover-truck off the ground when the engine's off, a mage who can unleash an unholy amount of damage, but tends to faint afterwards, a billionairess rock star based on Nina Hagen, and my covert-ops ninja-type guy with a taste for fine cigars, nonlethal takedowns, and a slightly luddite attitude towards cyber-modification.
We once torched an apartment by dousing it in cleaning fluids and then flicking a lit cigar through the window before rapelling off the balcony, and driving away on a bike driven by the shotgun dwarf. We were chased by a Lonestar bike trooper, who promptly went off the road when I put a throwing knife through his front tyre. Meanwhile, the rest of the team were ruining the career of the apartment's owner, who had proved a little disloyal to the Yakuza, by broadcasting a live feed of his wife in a compromising situation involving the elf and the mage, who was using illusion magic to disguise himself as a famous action film star, who in turn had been dosed with extra-powerful laxatives and was stuck in the toilet for the rest of the night. The feed was broadcast by the Dwarf decker, who used the line: "Hey, Mr. Yoshino! I didn't order your wife WITH SAUSAGE!!!" before broadcasting the footage onto the large screen at the international film festival Yoshino was attending, cut to Beethoven's "Ode To Joy". The footage won "Best surprise film".
Top THAT in a PC game.
