Mentalepsy: I don't care about the multiplayer, but I'm not going to buy it without knowing a) what kind of DRM is on it
According to [url=http://www.ecto-web.org/~spookcentral/scblog/index.php/2009/06/13/ghostbusters-video-game-pc-readme-file]the readme file[/url] it uses everybody's favourite, SecuROM. Unfortunately I can't find much info about activation limits and so forth.
Atari's previous PC release, The Chronicles of Riddick: Assault on Dark Athena, used Tages rather than SecuROM, and it had activations that could not be reclaimed with a tool or when uninstalling; after you use them up you have to phone tech support and beg for more.
