To those interested in Stronghold Crusader, you may hold up and wait for Amazon's "2K Strategy Pack
" since it includes the Stronghold Collection + BOTH Civ 4 and 5 Complete Editions for $20. Pricier than this, but you're getting WAY more stuff. Lords of the Realm looks pretty interesting though.
The next two seem to be the first pair of games that break genre, as one of them is a point and click adventure game and the other a side-scrolling action RPG. These are pretty new games too and The Whispered World is $14.99. Kind of an odd day.
