I'll have to pick Sony. Many of the games and series I love come from third party developers, and show up on Sony systems (makes sense with the sheer number of people who have owned the PSX and PS2). I also love some of their first party titles, such as Gran Turismo, Ico, and Shadow of the Colossus. At the end of the day though, there's a reason I own just over 50 PS2 games, and that's simply because more great games are showing up on Sony consoles if you ask me.

As for the other options; Microsoft's third party support for the Xbox has been rather forgettable with anything truly worthwhile generally being on other systems as well. And their first party titles are a non factor in my opinion. The only one of note is the Halo series, and I was playing better FPS games on my PC six years ago or more.

Nintendo, god love 'em, has some of the most recognized and loved franchises in the industry, and in the past have made truly great titles. Unfortunately, these franchises suffered on the GC if you ask me. Titles like Mario, Mario Kart, Zelda, etc. really only offered the same stuff we had pretty much seen on the N64, but less of it, and weren't as well done and ambitious as previous incarnations. I personally think that their major series have taken steps backward in moving to the GC, and it really dissapoints me. Here's hoping for some improvement (or perhaps even just some news on) these series future incarnations on the Wii. Hopefully they can rally some decent third party support for a change as well, though I'd be surprised if that actually happens, new controller or not.
