After being rather excited by the Heavy Rain trailer i decided it was time i finally gave Fahrenheit a go. These days i find myself more immersed by consoles than i do the PC so have been looking for an original xbox copy, which i have found. Now i know this can be bought on the xbox marketplace for 1200 points but i've also found it, new, on disk for £5.85. Am i right in assuming if a game is available on the live marketplace the disk version will also work with the 360?
