I think that the main problem with RE:Revelations sales performance is that you just can't buy it on the high street at the moment. I've been to a lot of different stores like HMV, Game, Gamestation, Smyths and Toy's R' Us but nowhere stocks it.

A lot of gamers buy from the high street and even rely on trading to afford new titles or just impulse buy when they go in-store.

I've not brought it myself yet as I've no time to play it but I may get it in the next few months.
