It's great that you've put up a way to support OFPEC by buying Arma, but I prefer having the box and disc. Could you consider having an option for us through Amazon Associates, preferably the UK store? I once requested this when Resistance came out, but then you couldn't because of the TOS between you and the host.
I hope I can try out Queen's Gambit this Christmas (need to install XP though, haven't had any luck with Vista and a 8800 GTS)
