Dark Sun - Shattered Lands
linky linky!
My alltime favorite game. Play it through, then read a faq and find all the areas and missions you missed (as well as awesome treasure - why else play a D&D game?
) The only bugs I've ever encountered in this game are balance related - there's a good chance that when a wyvrens hit you, they'll do an INSANE amount of poison damage that no character can survive, and you end up fighting A LOT of wyvrens in a manditory mission. Save often, and you'll do fine.
It's sequel (Wake of the Ravager) blew because of too many bugs - but for my turn-based dice-rolling tastes, there's nothing better than Shattered Lands.
