I primarily game on Sony consoles and PC.
I play strategy/WRPGS/FPS on PC and everything else on PS3/Vita including some exclusive FPS games.
I'm overall happy with what I get from Sony 1st party and they continue to get great 3rd party support (PS3).
I love specific genres on PC and there are some experiences which can't be replicated on consoles IMHO.
I love Microsoft for PC only (Win7). Hate their policy on pay to play online (360).
Neutral about Nintendo as they are going out of their way to not appeal to me (Casual and non mature games).
Slightly positive about Valve.
Love Good old games. (www.gog.com)
Used to be a huge fan of Blizzard and I still love their starcraft series but I lost a lot of faith in them after the clusterf**k that was Diablo 3.
edit- My first console was the Sega MegaDrive/Genesis and I loved it. I then made the switch to the PS1 and have stayed on with Sony consoles ever since. Although I have been seriously tempted by the 360 and have also owned an X-box in the past. Loved a game called Sudeki on it :) .
