You have to get a game related tatoo...

[dfphetteplace]

I have the Triforce on my left arm.

 

[Griffolion]

I'd definitely get the assassins creed symbol on my arm or something .

 

[jakel_hybrid]

I have been thinking about the Lambda symbol on my left arm

 

[Fetzenfisch]

I would NOT get this on the chest but apart from this i love it

Spoiler

 

[Pikey Mikey]

I'd probably get the Thousand Sons insignia (my favourite chaos legion) on my arm/shoulder, or Tzeentch's icon (Warhammer 40k). And maybe the Crimson Omen from Gears of War (logo, the cog with a skull in it), I do love that game =)

 

[Use_Imagination_here]

One of the weak spot symbols from SotC on the back of my neck.

 

[Mr.Squishy]

All the different DnD dice either circling my arm or down my lower arm.

 

[countrysteaksauce]

It would definitely be Agent 47's barcode tattoo.

I've always said if I were going to get a tattoo it would be a barcode.

 

[James Crook]

I want a "13" tattoo on my back in the fashion of the Fallout Vault jumpsuits

I would NOT get this on the chest but apart from this i love it

Spoiler

Looks like Sam & Max... is it?

 

[Lazy Kitty]

A Guild Seal from Fable.

 

[Blow_Pop]

I would get the one one of my friends drew for me. I can't find the drawing at the moment but it is an old school tv that is fried and on fire and a melted atari 2600 with the controller melted.

And I'll probably throw in the colossus' weak point from SotC into my punk rock goth gamer tinkerbell tat that I drew in high school

 

[phantasmalWordsmith]

I'd probably have an obscure quote going across my back. Something meaningful or just plain funny.

 

[WhySoElitist]

i know it is unoriginal but i would get deadmau5's tatoo

 

[Mistermixmaster]

the s.e.e.s. band from persona 3 is going to go on my left arm

Darn it ninja'd D:

Well, it would be either that, or something Valkyria Chronicles-related, but I dunno what.
Probably the Scout or the Shocktrooper insignia.

Where I'd have them I dunno though...

 

[The Unworthy Gentleman]

The three chain links on my wrist as Jack has them in Bioshock and the Assassin Insignia. I don't know where I'd put the Assassin Insignia so it's a maybe, but I definitely want the chain links.

 

[Flack]

I did.
I have this on my right arm just below my shoulder.

EDIT: Fable 3 industrial.

obviously not the sword just the black design

 

[Versuvius]

Brotherhood of steel badge. Or the chaos undivided star.

 

[Brownie101]

So many choices...

Spoiler: Nurgle's Symbol. All hail Grandfather Nurgle! Left Shoulder.

Spoiler: Skyrim Logo. Right Shoulder.

Also: Pic of an awesome tattoo because I can.

Spoiler: Its a Warhammer Fantasy tattoo taking up the guy's entire back.

 

[SangRahl]

I'd take the Polecats logo from Full Throttle... probably behind my left shoulder.

Spoiler: Either the whole design from the game GUI (with Prospect in the place of Polecats), or just the central CP swirl...

Another I'd thought of was Orange/Blue Portal symbols, on opposite sides of my calf. (or maybe PA's "infinite slide" design, outside calf)


*Edit:
Wait... I forgot I designed this back when I was part of the modding community for Fallout3.
I'd put this square on my shoulder.

Spoiler: Brotherhood of Steel - Stealth Recon unit insignia
