OK
now to the Mac port and the infamous DRM.
When I first got this game it wouldnt work. Well, it would launch, and give me a warning about needing Mac OS X 10.6.3 which hadnt been released yet. After that it would play, but the performance and glitches were terrible to the point that I just stopped trying until installing the OS update. At that point things worked much better, and overall I found the performance in terms of bugginess and stability to be about the same as the PC version
which really isnt such a great compliment. I had a few crashes, but more often saw graphics glitches and textures that would blink in and out, and other graphical oddities. In terms of overall performance, the Mac version was DEFINITELY slower than the PC version, so I would call this a mediocre Cider port.
As for the DRM
it is intolerable and unacceptable. The DRM is this: you need to go through all of the normal serial number and online activation hoops, but beyond that you also need to have a constant internet connection to Ubisofts servers. If that connection drops ON EITHER END you are booted out of your game. Originally the boot-out would lose all progress from the prior checkpoint, but an update made it so the game state was saved at the moment of connection loss
which was at least a step in the right direction.
