I've read a few reviews for both Fifa and World Tour Soccer, and opted to get the latter as it got much better write ups!
Also, gam3r, if your in the UK, I suggest getting a PSP off eBay. I've done a fair bit of research into things like paying tax, delivery etc. and found that the best place seems to be eBay.
I ordered mine earlier today off a shop on eBay, and paid £173 (incl. delivery and insurance) in total, for a value pack, with a very very very small chance of paying tax (they mark it as a gift and value of £36). It may sound like a lot when compared to Lik-Sangs £140 odd value pack, but if you add shipping onto that (£17 I think) and the fact that you'll most likely have to pay tax (£40 - 50), eBay is definately the way forward.
Here's the link to the eBay shop of the company I'm getting mine off.

They have amazing feedback, and for the total price, say you should receive your PSP within 3 - 4 days through FedEx.
I even e-mailed them and asked what would happen if my PSP get lost along the way, as if they were to mark it as valued at £36, then I would obviously not get all my money back. They got back to me within about half an hour, and said that if the PSP got lost, they'd send out another one, free of charge!
Service or what!
So any doubts, just e-mail them
