Question

Can PS Slim GB play PS games?
I have heard that some versions of the PS can play PS games, but I am confused about which ones can, and some can only play a few PS games etc. I was wondering whether a PS GB can play PS games.

Answer

Most PSs can only play limited PS games. Though many of the good ones are being resold as HD enhanced versions which can be bought on disk or installed via PSN store. Im particularly looking forward to MGS trilogy due out soon
