does anyone know if i can buy playstation 2 games in the US and if they would be useable in the UK?
You can use DVD Region X
It lets you play DVD’s from other countries on your PS2
If you have a mod chip in your PS2 the NTSC format games purchased in the US will be playable in a PAL format country (including the UK).
do ps2 games from US work on the UK ps2?
If you have a mod chip, yes. Otherwise, no.
