Several weeks ago I went to a massive arcade in central London with a group from an Internet message board. All of us were gamers, none of us mainstream. Nary a "Tomb Raider: The Official Licensed Soccer Game" would be found in our collections.
The arcade had all sorts of machines in it: racing, shooting, sports, beat 'em ups, dance (on which South-East Asian players held court) and even dodgems. Naturally my group gravitated towards the most hardcore and leet game available - catching plastic ducks with magnetic fishing lines.
The interesting thing about our party, apart from the woman dressed as a Gothic maid, was that when people weren't playing games, they weren't interacting with games. If one wasn't a participant, one was an observer. There wasn't an in-between. "Why is that interesting?" I hear you ask. "It's always been like that," you insist. Actually, it hasn't.
When I was a child I used to go to the seaside on holiday. The resorts we went to always had arcades and I made a point of visiting them. I'd have couple of pounds in 10p coins and spend it on titles including Super Sprint, Dragon's Liar (which I never got the hang of) and Star Wars. Even when the money ran out - it never lasted long enough - the fun didn't end. I 'played' the games anyway.
