I've always loved Discworld but when I recently looked for my original game disc it was nowhere to be found so I just purchased a bundle off eBay which included Discworld 1 and 2. Reading a few web pages, I noticed that there were several versions of Discworld 1 released with the first version being very buggy apparently. The next version (Directors Cut) was said to fix all the bugs. Now for my question. Can you tell which version is which by looking at the discs? I ask as my disc appears different to all the other Discworld discs I've seen on eBay.

Here's a closeup pic from the eBay listing:

And here's a pic of what the other discs on eBay look like:

Before anyone asks, I haven't received it yet so I'm unable to check the disc myself so these pics are all I have to go by unfortunately.
