TRIVIA: Game designer John Dale took inspiration from the classic arcade games ASTEROIDS and JOUST in coming up with the concept for THE GAME OF HARMONY (aka E-MOTION). In a 1990 interview he explained the thought processes behind his conception of the game:
"My job is to have ideas - I just sit around and have them. There was a little bit of thinking about the fact that there haven't been many games which use the 'Asteroids' type motion. You know: rotate and thrust. But at the same time we thought: 'What can we do that's different to Asteroids?' We had the idea for the ship that rotates and moves and then we thought: 'Well what's it going to do if it's not going to shoot things? Let's try pushing things around and see what we can do.' And we did."
"You push two different coloured ones together and they become a pod.... that's an idea from Joust (an ageing Williams arcade game, which unfortunately only ever made it onto the ST, and even then not very accurately). You know, when you kill a bird it drops an egg? Well, if you don't get the egg it hatches out into another bird. So we kind of 'borrowed' that idea, in as much as you generate pods, and if you don't get the pods they grow into full size balls again. So the idea just got built up, really."
