Forgotten Realms is part of D&D. Baldur's Gate, Icewind Dale, and Neverwinter Nights all take place in Forgotten Realms and are definitely AD&D games, though they don't use it in the title. More obviously there is Forgotten Realms: Demon Stone for Xbox. Xbox also has a game called D&D Heroes. Pool of Radiance also takes place in Forgotten Realms, although in that case they put the AD&D name in the title. Pool of Radiance was actually the beginning of a series. Its sequels were Curse of the Azure Bonds, Secret of the Silver Blades, Pools of Darkness, and Forgotten Realms Unlimited Adventures. Eye of the Beholder, previously mentioned, has two direct sequels as well.
