I purchased all the D&D games this weekend and I seem to have gotten an extra D&D game
DragonShard. I didn't see this in the list of games. :) What a pleasant surprise.

Was this part of the sale? I couldn't find anything about it.

Well, it is one of the games included in the sale, but it's not free at all.
Maybe you missed it because the full title is Dungeons & Dragons: Dragonshard?

That could well be. I only had three of the games already, BG1/2 and NWN. I noticed tower of elemental evil or whatever actually made my purchase cheaper.
