Fps-Halo 3

Tps-Gears of War 2

WRPG-Fable 2

What's next? Fastest selling strategy game (Halo wars)

                      Fastest Horror action game (Rezident evil five)

                      Fastest racing game (Forza 3)

That could be said for other consoles too :P

Sorry but that prize is for MKWii and maybe GT5

I find it amusing how you split up shooters into third and first person and make it "Western" RPGs. If they were actual genres instead of sub genres, they'd only have one. I can do it for Nintendo too!

Platformer - Some Mario Game
Role Playing Platformer - Some Paper Mario Game
Arcade Sports Game - Some Mario Sports Game

See what I did there?

That way it can be like this:
Wii:
Fastest plataformer: Mario Galaxy
Fastest racing game: Mario Kart Wii
Fastest Fighter: SSBB
Fastest Excercise: Wii Fit
Fastest Adventure/Action: TOZ:TP

:P

 you beat me =/

fastest multiplatform domination !!

if this trend continues, 360 as lead platform will continues.

Thread title edit:

Microsoft has a lot of the fastest selling WRPGs and Shooters.

Well of course but that is because those sort of titles are the more exclusive type most other types are are all Multiplatform (well actually WRPGs and JRPGS PS3 has none that I know of)which again sees 360 domination in most cases so he could be writing a very long title list..

Do you mean total sales, or first week? Do you count Single-plats only (I think you should). This generation only?

Because for 1st person shooter - Duck Hunt - 28.31M total sold.

Racer - Gran Turismo 3 - 14.87M or Mario Kart DS - 12.32M (will overtake GT3 soon).

Strategy - Starcraft. Has sold over 10M, according to the box mine came in.

Horror game - If you count single-plat, the Ps3 version may very well beat it. If you count single-plat, it won't become nr 1. Resident Evil 2 has sold 5.82M. For multi-plat, RE 4 has sold over 6M now.

WRPG - Kinda hard to say, as I don't know a lot about this, still for total sales, I'm certain several WRPGs have beaten 2.5M (which Fable 2 won't).

Using fastest selling ever would be stupid, as we only have data for 2 generations (and not even that).

But for this generation, this would be the list. Single plats only.

X360:

1st Person shooter - Halo 3 - 8.4M

Sandbox Game - GTA IV - 6.17M

3rd person shooter - Gears of War - 5.3M

Music game - Guitar Hero 3 -  3.51M

Role-Playing game. The Elder Scrolls Oblivion - 2.58M

Horror - Dead Rising - 1.78M

Now, that seems pretty impressive for this generation. But wait untill you see the Ps3!

Ps3:

None

See, it's not that good. No wait, I meant Wii. Look at Wii.

Wii:

Sports game - Wii Sports -  31.77M

Fitness - Wii Fit - 9.8M

Racer - MKWii - 9.32M

Fighter - SSBB - 7.27M

Platformer - SMG - 7.24M

Party - Mario Party -  5.59M

Action Adventure - Twilight Princess - 4.87M

Educational - Big Brain Acedemy: Wii Degree - 2.77M

Sim - Mysims - 1.24M

Still, OP is correct. 360 does very well.

One thing that makes it even better though, if you add in DS and PsP, I think it would go like this.

DS > X360 > Wii > PsP = Ps3 (I think both are at 0).

Look at Wii's list. What does DS take out?

Sports game - Wii Sports -  31.77M

Fitness - Wii Fit - 9.8M

Racer - MKWii - 9.32M

Fighter - SSBB - 7.27M

Platformer - SMG - 7.24M

Party - Mario Party -  5.59M

Action Adventure - Twilight Princess - 4.87M

Educational - Big Brain Acedemy: Wii Degree - 2.77M

Sim - Mysims - 1.24M

 So then Wii is stuck with 4, whereas X360 loses 1 and ends at 5 (DS has 10 or something at least)

So OP has a point.
