I'm a little late to the party but whatever. Si, if you stop making NSGP or start losing your faith in yourself to make an awesome game, that is too bad. I have played all of the New Star games that are out for mac, and I am planning on buying SLR and NSGP if I can near my birthday (in a couple weeks). I have played the NSGP demo to death, and it would be a pity for it to be the last in the series. Just the other day I had the urge to play an F1 game, and there NSGP was. (Unfortunately it is Intel-only so I couldn't play, but the fact that I knew there was just the right game for me makes me happy). So Si, keep doing what you do amazingly, making games.
