so 8-9 games sold 50mln copies on 270+mln consoles compared to 3 games that sold 25mln copies on 50+mln consoles. there's nothing better than fair comparison, right?

it means that when xbox brand would hit 270mln consoles Halo franchise would hit 135mln games sold and if ps brand would sell only 50mln consoles there would be less than 10mln GT games on the market.

Eh, no. 

The previous 4 (not 9 for god's sake) GT games made up a huge chunk of that 50m, the others clearly weren't intended to sell shitloads. And if youu are going to be silly like that then you might aswell include Halo Wars etc into the Halo mix.

So yea, you are really misleading and biased.

lol, another sony fanboy?

Gran Turismo series: Gran Turismo 1, Gran Turismo 2, 3 Gran Turismo Concept ps2 games, Gran Turismo 3 A-Spec, Gran Turismo 4 Prologue, Gran Turismo 4, Gran Turismo HD Concept, Gran Turismo 5 Prologue 10 games

Halo series: Halo 1, Halo 2, Halo 3,

even if i add Halo Wars(even though it doesn't have anything to do with shooting like Halo main series unlike all the Prologues that were OFFICIAL GT main series games) then we have somethin like 27-28mln copies sold on 50mln consoles LTD compare this to 50mln copies sold on 270+mln consoles LTD if you're keep trolling like this then stop saying that GT series is owning Halo series sales when it's obvious it doesn't.

Yea, I guess anyone who talks sense nowadays is a 'Sony Fanboy'

You are so biased. You put in 5 GT games that are meaningless yet you leave out Halo Wars and Combat Evolved etc. Pathetic. The fact is that 4/5 GT games have sold 40M and more, and 3 Halo games have sold 25m games.

Stop putting in stupid install base figures too, or you are digging yourself a hole. For example, you know Halo is on PC too...............whats the size of the PC install base? 

Halo: Combat Evolved IS Halo 1 also Halo series sold 25mln copies ON the consoles. who is pathetic and who is digging a hole here?

main GT series games excluding all the Prologues - 45mln copies on 250+mln consoles(18% userbase),

main Halo series - 25+mln copies on 50+mln consoles (50% userbase),

guess i can say that series is way stronger brand than GT series since just one game outsold all main GT games combined.

^ Lol

Install bases don't effect GT sales. Look up sales figures for all the games and the console install bases at that time.

Mama mia

Is all I can say.

how the hell can you even compare piece of crap Halo to GT?

Halo is not even close to being the best FPS there is, NVM better than the best driving simulator.

^ GT isn't the most popular racing game. Halo IS the most popular shooter.

America: Halo
Everywhere else: Gran Turismo

as simple as that... Halo is a mainly american phenomenon - of course it also sells shitloads in Europe, but the hype is nowhere as big as in the US.
