There is nothing wrong with getting a tattoo. There is nothing wrong with asking a tattoo artist what would look good. A quality tattoo artist even if they'd never played the game or understand the reference can tell you whether the tattoo will turn out well long-term in terms of how it'll age. It's actually probably smarter to go this route because they won't be biased toward or against a character or quote. They are simply there to help you design a quality tattoo. You should come up with a short list of three or so games and look try to come up with three rough ideas per game. Take these to two or more tattoo shops and let them give you their inputs and appraisals. If that sounds like a lot of work, remember that this is your body and it's worth it.
That being said, the Tatau from Far Cry 3 is a great tattoo, and furthermore, a great video game tattoo. Two birds. One Tatau.
