I don't have any yet, but I have all of my tats picked out and placements as well. My sister is drawing up custom game inspired collage sleeves for me. The rest are mainly video game inspired but a few are music inspired.
There is nothing wrong with game tats IMO because everybody uses a tat to fit their personality. If gaming is your thing, then why not ink up with it? Just make sure you think long and hard about what you get.
