Slitherine

Not sure about exact date though: official website says 07/07/2011, at slitherine product page release date mentioned is 10/07/2011 and 11/07/2011 at matrix.
But anyways, what kind of surprise from developers would you like for that date? Possibly massive discount, patch with new content or maybe something else?

A discount on every Panzer Corps expansion I already bought would be... uh... ah well.

I just bought the game. I don't think this even requires a special occasion - it would be nice if they bundled all the DLC into a single package.

since I just bought this game also, I agree with the idea of a bundled package of the expansion packs at a special price!!

lol how about allied corps or is that asking too much
