Xenoblade

Because of the battle system, story, tactics and the music,

I'm gonna say Halo 4.

It has my favorite multiplayer and I could spend countless hours playing that.

BioShock for me, with Super Mario Galaxy a very close second.

To me, BioShock is emblematic of the genre mishmash that defined the seventh gen. Part shooter, part RPG, part adventure game, BioShock encompassed (and transcended) several genres at once, and did so masterfully. The shooting mechanics are stellar, the art direction is spectacular, the firefights thrilling, the freedom of choice liberating. It's one of those rare games that keeps you coming back for more, and stays with you long after the credits end.

Fallout 3. It expanded what the idea of an RPG could be. It was an open-world FPP game that let you approach situations from just about any position you wanted. Sniper rifles, melee weapons, heavy guns, armor, bolt-action rifles, even flame throwers could be your weapons, or if you preferred, you could use your verbal skills, or stealth, or hacking ability. So much variety, so many things to discover.

On top of that, one of the best settings in all of gaming; dystopian but unique, apocalyptic but teeming with new life-forms. It's a game that creeps into your imagination, where the next step you take is up to you.

I still remember my first encounter with a Death Claw. It was just so bad-ass that I loved it despite being one-hit killed. I remember when I first stumbled on a Super Mutant Overlord in the center of the damn map. I remember getting the Super Mutants and the Brotherhood of Steel to fight so I could loot their stuff. I remember all the fantastic humor hidden under the surface.

I don't know how many hours I spent in that game but, especially when you factor in mods, it was a LOT. So many of the things that I wanted from a game, I got from Fallout 3, even though I didn't know it until I played it. It was truly a game-changer for me and I want more like it.

Damn if I don't want to play it again.

Hard to decide between Journey and Dark souls.

Journey was an incredible unexpected social experience. I never would have thought 20 playthroughs through a linear game could all feel so different. Amazing to explore behind the sign posted path by keeping each other in the air to reach unreachable places, with only the most basic form of communication available.

Dark souls' world is firmly etched into my mind. I don't have to boot up the game to visit every nook and cranny. The immersion level in that game was better then anything else last gen. Never have I played an rpg with such a sense of accomplishment. From being totally lost and scared to make a step, to dodging confidently through shortcuts to find the most efficient route on a 3rd playthrough.

I guess I'll chose Journey as that doesn't have a single flaw, while Dark souls, as great as it is, has several downsides as well. (Need for wiki to understand the basics, forced invasions, no pause)

Really Halo3 enjoyed the Single Player, enjoyed the 4 Player Coop Campaign pretty damn much, which wasn't very Common back in the days. Didn't Know for sure, but Maybe it was the First 4 player Coop on Consoles?? Forge was Fun as Well. Especially MP was Great, enjoyed Hours playing online.
Soundtrack is still the greatest of all Time for a Video Game. When counting the Add on Halo3 ODST to the Halo3 experience Firefight was top Notch fun

Blur

for me, the combination of a good arcade racer with power ups and very chaotic gameplay was just a golden combo.
to bad bizzare creations isnt around anymore.

Xenoblade Chronicles because of the huge world to explore where every area is different, great combat, many quests to solve, great characters, great story and most of all one of the best soundtracks i have ever heard

Uncharted 3.
Great story, and great online which includes co-op.
The dialogue in that game is what most high budget movies wish they had.

While characters in most other games stay silent during gameplay, in uncharted the characters keep interacting, so it keeps you interested and perfectly bridges the cutscenes. Even when youre climbing, there will be jokes exchanged between the characters. The amount of detail is incredible.

Then theres the variety of locations you get to play in, and again, they are very detailed, not only the textures but also the effects like fire, water and dust.

Apart from red dead redemption, nothing comes close to U3 as an overall game of the gen for me. Uncharted made the most of its linearity to beat Red dead redemption.

I cant pick one overall tbh.

PS3 -God of war 3 - because it was fun as hell and still one of the best looking games even now.

X360 - Gears of War 2 - I played it over and over again just because it was fun, I never did get the seriously achievement for 100K kills though.

wii - wii sports - a ton of drinking and fun with friends with this one.
