I actually have both disks for the original games (Mac) but I had to buy this copy out of frustration as I never have the disk on hand when I want to play. I've been playing this game at least once a year for the last decade and I was happy to see they did a good job with the patches. Moving to OS X with this game was a somewhat buggy experience before, but they've smoothed out the more irksome issues. The only downside is the screen scales oddly at times (when it cuts for videos), the sound effects are different, and the action occurs so fast at times it's easy to miss what happened.
