Some have already said it and I agree: everyone "won".
People got arguably the best 3D Mario games and therefore 3D platformers of all time with the Galaxy games, Metroid Prime 3, Zelda Twilight Princess (I also liked Skyward Sword), Donkey Kong Country Returns, Kirby's Epic Yarn, Xenoblade Chronicles (one of the best JRPGs around and basically the "start" of Monolith Soft greatness).
Playstation 3, while not as great as PS2, was the last good thing Sony delivered. Their first party might actually have been the strongest in that generation. We got the Motorstorm games, Wipeout, God of War 3 (the last good one), the Killzone games, Resistance 3, Sly, the Uncharted games, The Last of Us, Tokyo Jungle, Demon's Souls and many other great games.
And Xbox360 was obviously the peak of Xbox. Was a third-party powerhouse and it was when Microsoft's first-party delivered banger after banger. Halo 3, Halo Reach, the Gears of War games, Fable 2, Forza Horizon started on 360, Project Gotham Racing (RIP) 3 & 4, Viva Pinata... all great games.
Console ecosystems were still simple and not the service-based overpriced subscription hellholes that Microsoft, Sony and Nintendo are trying to trap consumers in.
