Looking at selling these games:
Call of Duty Modern Warfare 2 (no manual) - £10
Halo 3 (no online disc) - £3
Assassin's Creed 2 - £5
Racedriver Grid - £3
The discs are scratched but all worked fine for me when I just tested them (and have worked fine in the past).
Individual price of £21. Bundle price of £17.
AC2 sold to someone else as part of a bundle (in another thread).
Halo 3 & Racedriver grid sold to ebbz139 & ants97
