Bioware and Black Isle Studios are the best combination ever happened in PC RPG industry. They developed some of the most legendary games, including Baldur's Gate series, Fallout Series, Planescape Torment, Neverwinter Nights series, Knights of the Old Republic, Jade Empire and now Mass Effect.
Ironically the games up to Placescape were published by Interplay. Interplay also laid off the whole staff of Black Isle Studios before their own eventual demise.
Can't help but wait for Bioware's upcoming MMORPG and see if they can top the competition.
