Which game(s) are you a fanboy of ?

We all know each other well enough on GB to know that when we say fanboy, we dont actually mean closed minded biased fanboys with lots of rage and hostility.. it's just a fun way to say "a fanatic" 
So, list up to 3 games that you're a complete and utter fanboy of ! 
 
for me, it's always been 3 games : 

• Grand Theft Auto - ive been a total sucker for this franchise since i first played GTA 2 back in 1999 
• Assassin's Creed - the first game swept me off my feet, i played it like a an addicted maniac, and the second was greater and greater. playing Brotherhood now and it is blowing my mind and my ***** 
• Battlefield 2 - i get chills down my spine when i remember the first time i played it.. being a Doom/ Call of Duty/ Medal of Honor/ Unreal Tournament player back then, i had experienced nothing so sophisticated and great.

1. I like to think i'm a Max Payne / Crysis fanboy, but something about the former makes me feel im not worthy, and there are much crazier fanboys for the latter.. so i wont include them.  
2. I'm also sure that i would be a Mass Effect 1 and Silent Hill fanboy, had i played them when the time was right (rushed through ME1 & 2 and beat em the same month)

Mass Effect: I constantly hear people bitch about the first game, but I love it despite it's flaws. In my opinion one of the greatest games ever made. 
Alan Wake: I will defend this game 'til my death! 
THPS2: Who doesn't love this game!

Grim Fandango 
Planescape: Torment 
The Monkey Island series (the original 3 and the remakes) 
 
Then there's the original Fallout games and the Total War series. Could probably think of more.

Alpha Protocol
Shin Megami Tensei
Fallout: New Vegas

The Resident Evil series 
The Silent hill Series 
Battlefield Bad Company 2

Silent Hill 2 
Final Fantasy VII

Duke Nukem, Mass Effect, Battlefield.

Dead Rising 1 & 2 = the multiple play through aspect I love, can play through the whole game without really doing anything and have fun.
Pirates! : The amount of hours I threw into that game (original & remake), love it.
Fallout 3 / NV: Hours of wandering fun.
Goldeneye 64: So many glorious hours of wasted youth and could play while still holding my beer.
 
(other mentions: Left 4 Dead 1 & 2, GTA - ALL, Red Dead revolver & redemption)

MegaTen franchise 
Morrowind
Metal Gear Solid 4

Max payne 2
Mortal kombat 2
Medal of honor allied assault
BF2
GTA series

The Mass Effect- and Battlefield franchises.

Ratchet and Clank

Grand Theft Auto for sure. I obsess over every release.

I hear you about Assassin's Creed. But I do think 1 is so much better than 2. I would argue on forever about how good AC1 is.

Banjo-Kazooie 
Bully 
...Snowboard Kids 2?

Smash Brothers Franchise
Anything form the Behemoth
Ape Escape (Just the first one but I would be mad hype if they ever released a sequel that actually looked good)
 
EDIT - Gotta say timesplitters as well.

-Breath of Fire series (excluding Dragon Quarter) 
-Tales of... 
-Final Fantasy 
-Super Mario RPG/Paper Mario 
-Resident Evil

Pokémon: Best handheld games of all time. BAR NONE. 
Tekken: TEKKEN 'TIL DEATH, YOU CAN ALL KEEP YOUR STREET FIGHTER. 
Halo: Yep, I'm one of those guys. I still haven't had more fun online than I have with Halo 3. I need to get Reach and renew my gold subscription.

Assassin's Creed 
Mass Effect 
And yes, Halo.

MGS.

Elder Scrolls is one of my major loves. 
Monster Hunter as well as it doesn't get the love it deserves.  
And I guess I should put Pokemans down cause I play the shit out of them!

Im a sucker for Megaman

Max Payne, Metal Gear Solid, and Paper Mario are the ones that come to mind right away. I want to say Persona also, but, I've never played the older ones...

Tekken, although even I'll admit that Tekken 6 was pretty... meh. 
Timesplitters is the best console FPS game of all time. You know its true. Screw online, games are made to be played with friends in the same room.

Recently realized the Lego games (Lego Batman, Harry Potter, Star Wars, Indiana Jones) make me keep coming back.
Since Red Faction: Guerrilla I am a complete fanboy of that franchise (despite not liking the first game).
Mass Effect has a special place in my heart.

Silent Hill 3 - In my opinion, the best in the series.
Bayonetta - Probably the most fun I've had with any game, ever.
Final Fantasy IX - Also, in my opinion, the best in the series.

Anything made by Rockstar, and Psyonix Studios generally. 
 

GTA 
Elder Scrolls/Fallout 
When I still had a gameboy, P okémon.

I'm a pretty big fanboy of most of the stuff that comes out of these developers/publishers: 

• Valve
• Platinum
• Atlus
• Double Fine

Final Fantasy X.

Rocket: Robot on Wheels.
 
What? I don't have to be a fanboy for the big franchises and whathaveyou.

Bioshock (both games), Grand Theft Auto, Resident Evil, and anything developed by Bethesda, Remedy, or Monolith.

The Fallout Series 
Anything by Bioware 
Shin Megami Tensei

The Legend of Zelda 
Elder Scrolls  
Those are the only ones I'd call myself a fanboy for. 

Legend of Zelda. 
GTA. 
Blizzard games.

Tomb Raider, Legacy of Kain, almost anything by Valve.

The old school Resident Evil games, most definitely.

1. Shin Megami Tensei - I've played a number and enjoy them greatly.  I can't wait for more.
2. Dragon Quest - Same as above, but I am very sad that DQ X is on the Wii only.  Well, if it's ported to either handheld, I would consider buying one for it.
3. ... (Can't think of another.  No other game would make me do stupid things) 

Metal Gear
Uncharted
Mass Effect
Bayonetta

Max Payne
Battlefield
Dead Space 
Mafia 1 
Half Life

NHL series definitely. Been playing them religiously since NHLPA '93 on Genesis. Love em.

Tekken - easily my favorite game franchise. i continue to spill countless hours into Tekken 6 
Katamari Damacy - there is really nothing like these games and they are extremely fun to play. the humor is also great 
Okami - beautiful visuals and amazing story. i've played through it several times, something i rarely do with single player games

Freespace - Huge fan of space combat sims, so Freespace 1&2 are really close to my heart.
Mass Effect  - As a huge sci-fi buff, this one is a no-brainer.
Deus Ex - One of the greatest games i've ever played, sure the gameplay mechanics haven't aged that well, but the plot, the characters and the freedom to go through objectives as you see fit can still put other games to shame.

assassins creed ( all of them ) 
and fall out 3

Half life series  
anything by tripwire  interactive  

Alan Wake
Lego Indiana Jones
All The Fatal Frame's

Prince of Persia and Final Fantasy
 
EDIT: After reading the thread, I will shamelessly add Okami and Bayonetta.

Pretty much everything on my all time favourites list HERE, but the ones I really go nuts over, and wouldn't hesitate to cut a fool for saying something bad about them, are:
 

• Vanguard Bandits
• Every pre-EA Command and Conquer game except for Tiberian Sun. Especially Command and Conquer: Renegade. It's easily, if not, one of my favourite shooters of all time.
• While I hate what it has become with all the micro transactions they added to it, City of Heroes is one of my favourite MMO's. I put over 5 years into that game, and only stopped because of their recent trend to nickel and dime content that used to be given to us for free in updates.
• Dragon Age: Origins, despite it's many flaws, is one of my favourite RPG's to come out since KOTOR.
• Sins of a Solar Empire is one of the most fun 4X/RTS games I have played in forever. I can't wait to see what they add in the new expansion.
• Final Fantasy Tactics Advance is the only reason you need to buy a GBA/SP. I put well over a thousand hours into this game.
• While I have my reservations about what it will end up being, I have already shaved my head, got the tattoos, drank the Kool Aid and given over all my worldly items to The Old Republic. Though at this point, it's mostly just blind hope that this will be the Star Wars game I have dreamed of, even though I know it's not going to be.
