I wonder if license codes and game accounts of Enemy Territory: Quake Wars is compatible with Retail PC, Retail Mac and Steam version. I do not mean Steam key activation; instead usage of license code of one version with another version. As most you might aware, the retail PC version comes with a license code which players use to create online accounts to play the game online. Steam version however has its own CD key in Windows registry which stored in “HKEY_CURRENT_USER\Software\Valve\ETQW\licensecode” target. It can also be reach via Steam client’s “CD Key” option. What do you think? Are those keys and game accounts compatible visa versa? I am asking this because as far as I see ETWQ stocks on Amazon and eBay are about to be drained. Couple years ago there were lots of used or even new ETQW available but recently I detect way less than 100 all regions combined. According to SteamDB, there are about 25,000 owners of ETQW which is more than enough keys to increase the population.
Of course, using license code of ETQW which belongs to another Steam account is risky but I just want to increase the number of possibilities.
What do you think? Thanks.
