You see this is what i love about VGChartz. People try and pass off opinion as fact while trying to hide their obvious fanboy beliefs.
For example take God of War 3. People are arguing how succesful the game will be. Many saying it is a big franchise and sells consoles etc.. But let's look at the series sales.
God of War - Lifetime sales = 3.2m. First week sales = 172k.
God of War 3 - Lifetime sales = 2.5m. First week sales = 550k.
Those games had almost 120m PS2's to sell to worldwide and the series in almost 8 years has sold 5.7m units.
Now i'm no genius but in terms of game sales that is not so good. The fact the 2nd game sold less then the 1st does not look so good as it means popularit decreased for the series.
God of War 3 will not be a massive system seller based on it's previous records.
To put the sales in some kind of context. Halo ODST is on course to beat BOTH God of War games totals COMBINED, on a system with less consoles in the wild then the PS2 and with only a few months on release.
Now i hate Halo, but it shows how insignificant God of War franchise is when you talk about sales and more importantly talk about franchises.
God of War 3 will have zero effect on ps3 sales just as the last 2 had no effect on the ps2. I have no doubt it will be just another game to add to the list of games which did not sell as much as they probably deserved to ala Killzone 2 etc..
