Dude...check out Tesco, sainsbury, asda supermarkets...they all sell games and generally have good prices.
Game do pre-owned tho...nothing wrong with pre-owned as long as the disc is clean.
If you can get yourself. Into London...Hamleys is good...bottom floor. But you'll probably pay a premium, it is London after all.
(p.s. My middle name is Croydon...family tradition...I have folks in Warlingham, Croydon...Anyhoot, enough of my trivia.)
Enjoy your visit dude! You'll probably be glad to leave Croydon lol.
