well the price of ps3 games hasn't been announced, so who knows
but with 360 games they are generally 60 dollars
I don't know why it would be less than that, you're getting hl2 (a full game) plus the two episodes and other junk... a budget title seems unlikely
You are joking right i really doubt you will be able to get a ps3 game for £30 and since HL2 EP1 retailed at £20 it will be more like £49.99 or £39.99 at the least
