Success:

Multiplatform: going multiplat has never been so profitable

Failure

Exclusives...seriously after seeing sales for COD or Assassin creed tell me something more stupid than spending almost the same amount of money* to sell half of the copies.

*if not spending more...i suspect that trying to get the best out of a specific platform is more expensive than developing on one platform using half of its capabilities and then (crap)converting to the "poor sister" (either the PS3 or the X360 depending on the demographics) 

Sucess: is  gaming why?

there is 3 great consoles doing well many great 1st party and great 3rd party. because last gen was PS2 total domination that saw minimal 1st party from Nintendo and Microsoft 

Failure and Success: Wii

I think we all know why.

You wouldn't consider DK's return a real game?

Success:

Nintendo first party games-Overall I think best since Super Nintendo.

Online gaming

EA's rapage

Sony's devotion to quality exclusive's

Failures:

Sony's early price tag

3rd Parties ridiculous excuses/whining concerning Wii.

EA's rapage

Nintendo's soft stance on Piracy

Microsoft's red rings

Rail Shooters

misusage of the terms hardcore/casual

VIRTUAL CONSOLE...perhaps I was expecting something that could not be done. Huge letdown. Although monetarily probably successful.

Success:

-Wii

-DS

-Super Mario Galaxy ( :O)

-Fifa (So improved over PS2, stolen Pro Evo's title of best football game)

-Uncharted

-Online

-Trophies/Achievements

-Motion Controls

-Accessibility and inclusivity in games, even HD titles

-HD

-Self Improvement Gaming (Wii Fit, Brain Training etc)

-DL Marketplaces - PSN and XBL (not so much Wiiware)

Failure:

-Racing (why so few good racers? :( )

-Motion Plus

-Single Player Campaigns

-PSP/PSP GO

-Copycatting (Generic FPSes, Fitness software...)

-Xbox 360 Reliability - epic fail
