That's an easy answer. Longer term playability and polished game. See a excellent polished will continue to sell and be played LONG past a majoirty of good games out there.
Take Diablo 2, Star Craft. These games are still played and their gameplay is top notch. These games are over 5 years old now.
Most games on any platform console/pc just don't have that kind of staying power. Escpecially if the quality of the game isn't good enough to last 1 console. Much like Gears of War, God of War, Tomb Raider, Devil May Cry. All great games, but they are all front loaded experiences that just don't last the a console cycle.
It also comes down to design difference. Blizzard & Nintendo games are about experiences you find while most other companies are about experiences they design for you.
So top notch games that have selling power are games where you define self experience and excellent polish. Will continue to sell to the majoirty or mass gaming. That's why the ads in the paper you were looking at are the same. The games are just that well designed that they can keep showing them and get the sales.
Squilliam: On Vgcharts its a commonly accepted practice to twist the bounds of plausibility in order to support your argument or agenda so I think its pretty cool that this gives me the precedent to say whatever I damn well please.
