Legend CD install on Steam?
 

Hi.
Im pretty sure I'm going to be out of luck on this one but can I tie the retail CD version of Legend to Steam? and if so, how? Usually you just enter the cd key from the box but there doesnt seem to be a cd key

No, all you can do is to add King's Bounty's launcher to Steam, but it won't be a Steam game, thus perhapse it will take count of your statistics and your friends will see you playing King's Bounty.

Only Steamworks game can be fully added to Steam.
