Thief: The Dark Project, Tenchu: Stealth Assassins, Rainbow Six, and Metal Gear Solid all came out in 1998 and it looked like the genre was really taking off...
I haven't followed video games so closely the last few years, but it seems like light stealth elements have been taken up in a few games and there's been sequels to those franchises, but it never became a really dominant genre.
Any thoughts as to why? I'd think with all the new processing power and AI improvements, that you could make a pretty excellent stealth game to appeal to both hardcore gamers and more casual players.
I think people realized doing stealth for a whole game is too boring, but most action games integrate stealth mechanics now, or throw in a cursory stealth level. Even Halo has stealth, although I doubt anyone ever stopped to notice... it's like putting a karma system in Doom.
