It’s a sign of the times that when, a few years ago, I said “I design videogames” people would smile, nod and either look for something or someone else to talk to.  This does still happen at times but it’s now become more common for people to say “hey, that’s cool.  Bet it’s a fun job!”  I confirm that it is.  More recently still, and people have started to then go on and ask me exactly what it is that I do.  And that’s where I stumble a bit, because it’s not easy to quickly define.
