I understand how Strategiclayabout feels about the price, I was more than surprised to see a price reduction on the bundle just a little more than a month after AoC was released.
However, the $5 is going to an excellent cause: supporting the best 20th century strategic wargames available. If Hubert and Battlefront don't have our economic support, we won't have SC games (including the upcoming SC3).
If you haven't checked out their competition lately, I suggest you do so. (I'm intentionally not naming names or mentioning problems with the competition.) After you check it out, you'll be glad you paid the $5.
