King's Bounty: Crossworlds on Steam with pre-purchase?

[Saiko Kila]

I've got this as a gift today. But, contrary to some opinions, I can't gift The Legend to someone else despite having KBTL already purchased and installed. So, in this case the second copy of KBTL is wasted.

As a note, the editor is located in the TOOLS tab of Steam, and it requests more space than I have on my disc to install (after installing Crossworlds) - over 10 GBytes
