The 00s have ended, so let's see what our opinions are of the best games of the past decade, from the 1st of January 2000 to the 31st of December 2009.
This is actually very hard, as there is a large difference in terms of processor capabilities between the two dates, as in 2000 you had games like The Sims 1, THPS2 for the PS1 and Counterstrike (looked it up on Wiki, don't shoot the messenger), contrasted with 2009, where you have Cod:MW2 and AC2. I think the original Halo and Half Life should be considered for some of the best games, as they were great in their own right but continued spawning good sequel games throughout the decade.
Genre maybe?
You putted two of the greates FSP ever, but you must be a little more specific, as well as there is more in world than not seeing your head.
My top 5:
*Honorable Mention: GTA IV, Gears of War 2, Forza Motorsport 3, Need for Speed: Hot Pursuit 2*
5. Batman: Arkham Asylum
4. Modern Warfare 2
3. Assassins Creed II
2. Halo 3
1. Fallout 3
The decades best game was unquestionably Fallout 3. I literally have yet to play a better game in my lifetime (even better than AC2).
Hmmm, i'll go FLAE style.
5.ACII
4. THPS3
3. MGS 4
2. Half-Life
1.Halo 3
I putted Halo on the top not only for the fact that its a great game, but also because it has revolutionized the online gaming experience and has had an impact so huge on the industry and gamers that almost 3 years after it release.
And to finish FLAE style.
*HONORABLE MENTION*
Fallout 3
God of War
Conquer's Bad Fur Day
Forza 3
Gears of War 2
Killzone 2
I'm going to be consistent and go with Uncharted 2 as my favorite game of the "Naughties." Its the most cinematic game I've ever played, and I love it for that.
I can't really rank any of the other games I like above each other, so I'm just going to make them all honorable mentions:
Halo 1 and 2
Gears of War 1 and 2
Killzone 2
Resistance 1 and 2
AC 1 and 2, of course
Half-Life 2
Portal
God of War 1 and 2
Metal Gear Solid 2, 3, and 4
LittleBigPlanet
Batman: Arkham Asylum
Fallout 3
The Elder Scrolls 4: Oblivion
Uncharted: Drake's Fortune
InFamous
Oh, there are four others that aren't on my honorable mention list that I forgot to add:
Jak & Daxter: The Precursor Legacy
Jak 3
FarCry2
GTA: San Andreas
(I'm probably forgetting like 20 others as well)
How could I forget, Resident Evil 4
Uncharted 2 hands down.
Metal Gear Solid 2!
