Easy question: which platform would win a hypothetical "Platform of the Year" award this year? Needless to say, this is completely personal and only based on your own experience with these devices, no matter how "objectively better" any other platform may have done this year.
PS: I grouped the mobile devices into just one option because, let's be honest, even if they are big right now, the chances that a Giant Bomb user sees them as their main gaming console are slim to none.
PS2: Sorry if this was already done. I searched the forums and the results gave nothing.
I'll have to go with the PlayStation 3 (I don't have a gaming PC that can run many of the games that came out this year so I can't really say PC for this question)
PlayStation Plus really hit its stride this year with the Instant Game Collection, upping the Cloud Saves to one GB, and making a huge splash on the Vita right out of the gate
By far, Valve has shown it has the best deal for publishers, the best features for customers, and that it is willing to work continually on improvements to its interface and features, and will take the chance to provide new features, instead of simply following the competition.
In response to the growing trend of PCs being used as a traditional TV based console, Valve has provided Big Picture, a controller driven interface that I believe, is superior to anything currently available.
Steam has expanded its community features, and turned Steam into the largest gaming based social network in existence, streamlining the friends list and adding an activity feed showing what everyone on your list is doing.
Finally, Steam continues to expand into the indie space with Greenlight, while it is in the midst of a few growing pains - both Valve and devlopers tweaking the system to find something that maintains a level of game quality, while allowing deserving indies to get published sooner.
While the PC has pulled ahead of consoles in terms of graphical look and processing power simply due to the fact that game consoles remain on 2006 hardware, the biggest achievement for PC as a platform, is that it finally has the unified community and matchmaking service to compete with Xbox Live and the Playstation Network.
Well, I was new to PC gaming this year, so my vote goes there. There were just a ton of options opened up to me that I can't ignore. That coupled with the fact that there weren't any standout console exclusives really sealed the deal. I did rent and forget a lot of console games this year, but most ports now live on my PC.
