Very easy decision for me but still doesn't mean that there aren't a lot of good things in 2009. I voted for the DS and I think it is quite clear why it was the system of 2009. It had a range of big exclusives that released throughout the year. There was never a drought of a good DS game and could only get it on the system. Also had a large support range for all kinds of different genres and games. Then of course you had some of the best sales with the most successful launch of the year: DSi. Even with the success of the PS3 Slim, DSi simply just blew it out of the water. Nintendo kept sales of the system at dominance for the entire year.
Second of course for me goes to the PS3. Had a good amount of big quality exclusives such as KZ2, Infamous, Uncharted 2, Demon's Soul, and Ratchet and Clank: A Crack in Time. Not to mention the vast amount of big 3rd party games that released throughout the entire year and filled in the wholes between big exclusives to keep gamers happy. Second part of this is of course the great sales. Had a pretty bad first part of the year but turned it completely around with the successful price drop and PS3 Slim launched which was handled perfectly by Sony in the marketing department.
For the rest I'd say Wii is 3rd, followed closely by 360, probably tied with PC, and then of course a distant last for PSP. Wii gets 3rd for it's continued great sales even despite a summer fallout but return with big sales after the pricedrop. Also had a vast amount of great exclusives that released the entire year with big ones in holiday season. 360 falls just short of Wii mainly due to the lack of really any big exclusives till we hit ODST. PC tied right with it for big exclusive and a healthy selection of titles but a really a fall from grace as consoles continue to take over and no one stepping up to take over.
Finally, PSP at the bottom. Had a good selection of exclusives but never really had that one big exclusives to drop sales of software or hardware. But sales were way down over last year and Sony's only attempt to solve it was that of the PSP Go which is easily the biggest commercial flop since the Virtual Boy. Truly a sad story for the PSP commercially this year but not too bad thanks to at least a good selection of exclusives for its buyers.
