Arcanum also made the list, but I'm not objecting to that.
But IWD, NWN and ToEE make the list while the Ultima series, Arx Fatalis, Gothic, KOTOR, Wizardry, Might and Magic, Bards Tale, Nethack, System Shock, Deus Ex, Zork, Starflight, Krondor, Elder Scrolls, Dungeon Master, Wasteland, Eye of the Beholder, and many, many other important RPGs are missing from the list.
Fallout and IWD actually get two entires on the list.
