Thank you for the update! It is too bad it took so long though, really makes you hesitate buying it.

Good to see that this was finally released. At this point the only remaining issues with the GOG.com release should be the unavailability of DLC and lack of some Steam-exclusive features such as the online leaderboards. However, these are fairly minor issues.
