People who tell you to "grow up" because of a hobby you have are fools. Work hard and play hard! My friends are all gamers/programmers/SciFi peeps, so they're very cool with my arcade/pinball hobby. My mother hates the fact that I may sell my ToM someday so I can mix up the gameroom. My wife likes the games too. She doesn't really play much, but there are some games (vids and pins) I mention to her and SHE convinces me we should get them.
I do, however, get the face when I tell my friends prices of some games.
