No, it isn't. These games are definitely better than Gears: Metal Gear Solid 4: Guns of the Patriots, The Legend of Zelda: Twilight Princess, Super Mario Galaxy, Bioshock, and Grand Theft Auto IV.
These games are just as good as Gears and I would definitely make several points for Uncharted being better having played it and Gears to very near completion. Uncharted: Drake's Fortune, Ratchet and Clank Future: Tools of Destruction, Oblivion, Rock Band, Super Smash Brothers Brawl, Resistance: Fall of Man, Metroid Prime 3: Corruption, Kameo: Elements of Power, The Orange Box, Mass Effect (maybe), Halo 3, Yakuza 3: Kenshin!, and Call of Duty 4.
And these games will also definitely have something to say about what game is the best game of this generation: Final Fantasy XIII, Final Fantasy Versus XIII, The Next Team ICO Project, Fable 2, Too Human, Jak and Daxter: The Lost Territory, Infamous, Damnation, Tomb Raider: Underworld, White Knight Story, Uncharted 2, Resistance 2, Gran Turismo 5, God of War III, Little Big Planet, and Resident Evil 5.
"Personally GOW 1 was awesome. And to this day is in top 3 of the gen on any console."
