JogsterXL: These two required contacting support. Also, ArmA Gold, which is not on your list, required contacting support. (I have the emails with keys I requested back when I first purchased these and sent in a support ticket.)
I do not know if keys are still needed or can even be requested due to the ArmA games no longer being available here and the GameSpy server shutdown, but they were available at one time.
Seems like I somehow missed ArmA Gold's entry on the GOGwiki. If possible, I would like you to try with both ArmA Gold and Arma: Cold War Assault and see if they require the key for LAN play or if it is obsolete, now that the Gamespy servers have closed. Thanks for the info and I will add I.G.I. 2 to the list, for the time being.
DyNaer: untrue , you can access to the support section if you have those games in your shelves, and create a cd-key request.(other option and select MP cd-key request in the dropdown menu and input the name of the game of course) However i have no idea if the support could still deliver a MP cd-key....
this is for Spellforce Platinum / Spellforce 2 Shadow Wars, others Spellforce games don't have a mention about a CD-key in the support section.
OK, partly my fault. There is a support section indeed, but you can't contact support about the game. When I tried, it sent me back to the support page, rather than forwarding me to the choices about the specific problem (like technical issues in the case of multiplayer keys request).
The reason I mention Dragon Storm is because it was included in an older version of
kaliy's GOGmix.
