Well, just recently I decided it was the Elder Scrolls V: Skyrim upon its release. Anyone familiar with the series or title will understand why. 

Got way too many...

Xbox: All Halo, Halo 2, Halo 3, Halo Reach and Halo Wars.
Gamecube: Pokemon Gale of Darkness, and Sonic XD adventure
Ds: Glory of Heracles, Pokemon Black, and even Pokemon Diamond.
3Ds: Kid Icarus Uprising(COMING SOON), Super Street Fighter, Legend of Zelda, and Mario Kart 7.
Ps3: All Sonic Games
Wii: Just Dance, Sonic and the black night, Sonic Kart, and My Sim.
Xbox 360: Midnight Club Las Vega, and Assassin Creed
GameGear: Sonic the Hedgehog
PC: Eden Enternal, Combat Arms, Maple Story, and SPORE

Majora's Mask is my absolute favorite game of all time. For one, it had wonderful character depth, something you don't see in quite a few games. Secondly, it had great gameplay, as well as arguably the greatest swimming controls in any game. I also loved the dark overtone and art style, something we don't see in any other Zelda games except Twilight Princess. Furthermore, the music was phenomenal (Song of Healing is my personal favorite). It all adds up to an amazing and very artistic game which I personally think surpassed even the likes of Ocarina of Time.

After Majora's Mask, I'd have to say that Wind Waker is my second favorite game of all time (art style and attention to detail were amazing), and the inFAMOUS series were my third favorite games of all time (beautiful story and art direction, solid and enjoyable gameplay, and what I think to be the best voice acting of any game I've ever seen).

Hard to say, but I am sure that either Sonic Generations or Sonic Adventure 2 is my favorite, Nya~. They both were the height of Sonic's glory in the generation that they were made, SA2 being DreamCast and Generations being Modern, and they both were an all around enjoyable game, wether it's story mode or just running around.

What? Do we have to pick three's so many good games right? But I am leaning to the legend of Zelda games and other rpg games like Final Fantasy, but i also like playing Halo Reach, and as they said some where up on the page. Sky rim its game play and graphics cant be matched.

I have several favorites, actually, I could go into great detail as to why I like each of them, but that would take forever, and I'm in a lax mood tonight. =D

Final Fantasy VI
Faxanadu
Super Mario Sunshine
Pokémon (Any, minus the console games)
Persona 4

To name a few.

Why, I love Super Mario 3D Land. That game is the best Mario game yet!

NathanK17 :
My favorite video game would either be finial fantasy. I like most finial fantasy but I don't like the ones that are not free roam. The reason I like final fantasy is because they are long and hard to beat and there are many adventures and there are man great monsters and character.

Good question, I would have to pick final fantasy seven on ps1 I just think that game is perfect, can't find anything wrong with it

Legends of Zelda:Ocarina of Time.Sure you may seen tons of movie,shows,books and Mangas when the boy is set on a adventure but this is when Games was just turning 3D. It opened a lot of opportunity for gamers out there including the ones that 's a fan of the Series .

Well, I have two derivations of favourite video games.

--- MODERN ---

Currently, my modern favourite game is The Elder Scrolls V: Skyrim by a long range to my second favourite game.

Now, let me explain this before you ask for the reason. Skyrim is a far and massive game where it is literally your second life. You can be just a woodcutter for your whole life if you wanted to, or you could do a Whiterun guard impersonation, or instead of being a Dark Brotherhood assassin, you can be just a Nordic warrior. The diversity of the game is jaw-dropping. The size of the game is, at the very least, impressive. The graphics has absolutely blew past any of our expectations for the games of 2011 to 2012. I can't even get started on the lore of it, or the theorem of it, because it is indescribable, so to say.

That is my reason to have The Elder Scrolls V: Skyrim as my favourite modern game.

--- RETRO ---

Now, this is my second derivation of my favourite game, and it's primarily based on the RGR on Vizzed, and this might come off as not surprising to most people.

My favourite game in the RGR is Legend of Zelda: Ocarina of Time. I practically grew up with that game as a child, and it is literally the first game I've ever played in my life, so it's stuck with me forever. This is my darkest secret, but I'll just say it here. I have never finished Ocarina of Time. I've never actually defeated Ganon.

Let the gasps come.

There has been variety of games for me
but my Top 4 games would have to be
1) The entire Kingdom Hearts Franchise such as Birthbysleep,KH1,KH2 ect.... (many others!)
2) It would have to be for sure ModerWarfare, Blackops which ever you would love to call it.
3) All Pokemon Games since that was my childhood game. (:
And last but not least, 4) Which has been a very recent game Infinite Undiscovery.
Manly what I love is mostly Square Enix games. ^-^

For game cube its metroid prime 2 for ps2 A tie between harry potter and guitar hero games
for gameboy i enjoy harry potter games and for wii propbably mario

I have to say any Ratchet and Clank game except number 2 and 4, Metroid Prime 3, or Legend of Zelda Skyward Sword.

Mainly because they are all fantasy games and are action games, and have a LOT of depth.

For each console, my favorites are:
 - Nintendo -
    NES: Zelda
    SNES: Super Metroid
    N64: Zelda Ocarina of Time
    GameCube: Metroid Prime (1)
    Wii: Super Smash Brothers Brawl
    Game Boy (Color): Zelda Link's Awakening DX
    Game Boy Advance (SP): Final Fantasy V
    DS (Lite): Pokémon White
    3DS: Zelda Ocarina of Time 3D
 - XBOX -
    Xbox: Splinter Cell Chaos Theory
    Xbox 360: Halo Reach
 - Sony -
    PS1: Would be Final Fantasy VII
    PS2: Sonic Heroes
    PS3: Assassin's Creed Brotherhood

Resident Evil - The whole series in general. Resident Evil has a great story that blends well together throughout the series along with great character relations. 

Final Fantasy 7-9 - With 8 being my favorite. I'm a sap for a little love story here and there. Great character development, junction system, and triple triad

Honestly its kind of hard to say what is my favorite video games sense I have many. But honestly if I had to say what my favorite video game is I would have to say it would be Quest 64 for the Nintendo 64.

This game is a personal favorite because, in my eyes, its what started a lot of different rpg adventure games then others have. I mean, its really cool to play, you get to fight different monsters, each harder then the last, you get to learn very cool spells, and its really addicting. Its one of the many games I first started playing back when I was six years old. Its a game that I believe should be played always, even if your not a fan of the type of game.

A game that I find however to be a personal favorite is Turok. Yes it has different versions, but Turok 3: Shadows of Oblivion, was a classic. Reasons why I liked it because its one of the many Turok games that allow you to choose your character, thus choosing your path. And its many multi-player action is always a classic.

I would consider these games my favorite no matter what.

As of right now....

Skyrim.

It is the most complete game I have ever played, and I could seriously play this game forever. I just might end up doing that.

Who knows? I wonder if DLC will be made for it any time soon.
