Best quote from the author's article explaining how it was done (even though by his own admission he didn't follow his own advice in the case):
"If you want to make a game, make a game. If you want to make a game engine, make a game engine. But never, ever, make a game engine to make your game!"
I spent a good five+ years working on my own game engine to make my own games with it. Never finished a single game, or the engine-- but it was a fun learning experience so there's that.
