SMH has identified the following games as missing out: Legend of Zelda Wolfenstein Civilisation Ultima Online Myst Alone in the Dark One on One: Dr J vs Larry Bird Brain Training Halo 2 Metroid Final Fantasy VII Nintendogs Populous Pole Position Spacewar Adventure Zork Testdrive DonkeyKong Pokemon Personally, I would have had Dune II much higher, and Populous, Prince of Persia and Ultima VII would have been in my lists. Also surprised that no sports or driving games. Could probably make an argument for Guitar Hero too.
