May be I,m part of the analagous statistics brigade but my son in law bought a PS2 { for him and my grandson } sold on the PS1 kept the games it gave him a start libary ! , two of my second eldest daughters ex boyfriends traded up to PS2 kept old discs to play because they cost a fortune original 1st time round ..... in fact so did my son when he upgraded ! . In each case they were determined not to have to start from scratch and lose choice
......... hang on thats four , damn my senility
