Lucasarts is coming out with an updated Gamepack that will have Full Throttle, The Dug, Sam and Max Hit the Road, there might be more, but I'm not sure. The pack will be updated to work on all PC's, but I don't know if it will work for Mac. I have no idea when this is coming out though. Maybe it's just a rumor.
Hopefully not though. But if it's not, it's good Lucasarts cares about there old products..
