Waiting ages for this to fall <£10 and ive rarely seen it below <£15. An exellent tennis game even compared to tennis games on home consoles. Certainly the most playable and fun tennis sim around atm. Theres also a demo available on PSN if you fancy a punt.
Next cheapest is game gears @ £13.99 or PLAY @ £14.99 then everywhere else is £17.99
