ZEEKA, this has always been the case, the US have always had a larger range and also technology tends to arrive in the US first; then Europe follows suit. Majority of manufacturers will have a larger interest in the US as they also tend to have more operations in North America. The market is different in the US. Larger market and more consumers when compared to UK. However, UK doesn't fair badly when compared to other European countries.
UK consumer market will always be a couple of steps behind the US counterpart.
No hes right. Amazon.co.uk are terrible when it comes to extra goodies. This has nothing to do with being in the UK or USA. The UK get their own batch of exclusives such as the heavy rain special edtion box set. For these things i go to play.com or game.co.uk. Amazon do have excellent low prices like castlevania which i will be getting from here!
