Forgot to add, the other day I was moving my sons PS3 out my way, to dot some cleaning-as you do- and it occured to me it was really heavy. It also crossed my mind that it would be heavy for bringing from the UK. We got ours here.
The games sold here for the PS2 & PSP (not sure about PS3) are the same region as UK (and 90% are in english) so the originals play fine on a UK box but yeah, get it chipped if you can or most new ones sold in the "smaller" electronic retailers here are already chipped!
I had one of the 1st batch of original PS2s and its too old to be chipped but all the original "shrinkwrapped" games ive bought here work OK, just the "burnt onto a CD and shoved into an envelope" ones wont (unless chipped). Maybe its just Antalya that sell the region 2 games?
