I already have one of Pac-Man on my ankle (before anyone asks, yes it is more meaningful than a simple tattoo of a video game character) but if I were to get another tattoo it would probably be something colorful, like artwork from Okami. I would really love to travel to Japan to get it done in the traditional, manual style but I do not think that my threshold of pain is great enough.

The only tattoo I would ever get is the sprite of Sonic running from Sonic 2. That really symbolizes my entire childhood, and brings back a ton of great memories. Even when I'm old as hell I could see that and feel good.
Not technically a videogame character in it's origin, but mine would be a Klingon warrior holding a bloody Bat'Leth with either Kirk's or Gorn's head in his hands, with the Klingon symbol ghosted in the background.
Location would be right lower leg from knee to ankle to offset the dragon I already have on the left side from knee to ankle.
I would want it done by an artist well skilled in photo realistic inking.

I have this idea for a sleeve if I ever have the money. The guy from journey on my upper arm with the scarf wrapping around down to my wrist. The rest would be filled in with some of my favorite characters and other artsy game elements. I would need a skilled artist to blend it all together in a tasteful way.
