Prince of Persia:The Forgotten Sands Collectors Edition?

There are probably hundreds of 'Should I Buy' threads on here, but I would like to know...  
 
I have found the collectors edition of Prince of Persia: The Forgotten Sands for £14.99 (Which is about 25 dollars...I think) is it worth picking up? I have quite a few unfinished titles already (and some still sealed)...would I be missing out by not purchasing this or should I have already put in my card details by now? 
 
Thanks

uhm, i say no, it is cheap yes. but the collectors doesn't really add very much. plus that game will still be there if you want it, especially if you have unopened games!  

Okay yeah, I'll leave it then. I have a ton of games I need to get through already, most of which are better titles...Mass Effect 1 & 2, Demons Souls, Yakuza 3 and the list goes on. 
 
Thanks for the help. I'm not sure how this thread can be closed but I'm finished with it now.
