I installed this game from the original DVD on my new MBP with 10.5.5. I had to use the updated installer application which I found elsewhere to keep the installer from crashing. It performed very nicely but I had not installed any updates, so it was obviously running under Rosetta. After applying the 3369.2 Universal Binary update, the performance increased dramatically. It was already running great with max settings with the PowerPC under Rosetta version, but the UB update makes it somehow even snappier and FPS goes through the roof.

The down side is that after applying the update, the audio of the players voices no longer works. I tried deleting all my custom user data files and running everything at default and still nothing, so I guess the update changed it somehow. Too bad, because the voices are a real part of the fun. I don't know if it's a bug in the game or an incompatibility with 10.5.5 or what, but I wish there was a solution because it's still a fun game.
