Could someone explain it to me ? (Ps2 sales)

[Sleepyprince]

People, 

According to vgchartz, PS2 sold approx 140 millions units. If I look at PS2 most iconic games, a lot of them sold 3 to 6 millions. But the market was 140 millions owners. 

So, can we consider "flop" god of war 1, DMC 1, and other games that sell alike ?
