At least for consoles, I wonder how the list would break down if the numbers of sales were compared to the number of active consoles to get a "market domination" factor.
10 Million copies of Super Mario 2 release over twenty years ago compared to 13 million copies of Sims 2 in the 2004 market isn't really a fair comparison.
Of course, PC games never sell, they are only pirated (unless they're online play) so that's not a surprise.
Having missed everything in between the third Zelda up until Halo 2, I still think Ultima VI, the original Heroes Quest, and Wing Commander - Privateer are three of the best damn games ever made. I guess I better get up and go yell at some kids to get off my lawn.
