I'm a 21yr old university student. I used to love playing this game on my old PC. I've been itching to play it since and it's been 10 years.
The experience is far better than I originally remember, this is mostly due to the improved performance of new technology. I'd highly recommend playing this with a simple external mouse rather than Apple's trackpad/magic mouse because of how dated the game is. I've got fantastic use out of the game and it is definitely worth the price tag.
It has not crashed or had any negative results.
Estimated as a month, but it was closer to five working days (this was over xmas, and therefore doubly impressive).
I thought it was expensive (when compared to the price of the PC game, but you need to consider the game has been made accessible for Apple computers and was only intended for Windows).
6 month update:
I have played this game a hell of a lot. It's a nice contrast to the fast-paced online multiplayer games. I'd highly recommend the game, even with its price tag. The gameplay is smooth and offers a fantastic experience.
