There is the first (?) dating site for gamers (or for geeks, as indicated by the site).
So if someone has been out of the game for a long time, or he has no time for going out (and meet new people), this site is for him.
The site is Dateagamer and it's in England. I do not know if it provides support and for the other countries too, but so far has more than 150,000 players, as the site says.
Here's someone who thinks for gamers and their dating life 🙂
