Will Blood Money come to gog?
Kind of strange to see the first 3 games here for sale but Blood Money is not available.
Is there a legal reason?

Contracts got added recently, so there is currently nothing speaking against the release of Blood Money on GOG.

It has SecuROM at GamersGate and it's available at Steam so maybe it's DRM is the issue. Flat prices could also be an issue but I'm not up to date on which stance GOG is on that.

i don't know, Riddick had some nasty DRM and it still made it on here....Blood Money is likely. May have to wait till the next Hitman game while they are out promoting to see it here though
