Nintendo: Gamecube. Great games and best controller ever
Sony: PlayStation 2. Superb and diverse games selection, plus backwards compatible to PSOne
Microsoft: Windows 98 SE ^^ Yeah, never had any interest into Microsoft consoles apart from the fact that it pulled their games development from the PC to the consoles... and yet they wanted to strengten PC gaming with it? Yeah, no, that's how you don't do it!
