Capcom recently announced a lower priced, more appropriate limited/collectors edition for Resident Evil 6. RE6 Archives Edition includes Resident Evil 6, Resident Evil 5 Gold Edition, Resident Evil 4 HD, Resident Evil: Code Veronica HD + Resident Evil: Degeneration (movie). It's priced at $80 in America so will most likely be around £60 here.
Although if you own a PS3 you can get the RE6 Anthology Edition, which includes RE6, RE5 Gold, RE4 HD, RE3, RE2 and RE1 for the same price. So it's a better deal I think.
If the price is indeed £60 here I might find myself ordering this. £60 for all that is a steal I reckon!
