I'm out of the industry now, but I kept doing this for a while. I would want to "scratch an itch" and build a game out of hours. After a few attempts I realised I don't actually want to build a game, I want to build an engine
I was just browsing a few of your past comments and see you were in gamedev in Melbourne. Maybe we've crossed paths - I was at Blue Tongue until we were shut down by THQ, then Tantalus for a year or two, then freelance for a while, and the last seven years I've been at Sledgehammer Games Melbourne.
