FYI The Dead Age Bundle includes the 2 Soundtrack, yet this site allows you to buy the Soundtrack after the fact because it doesn't acknowledge you already own it in the Bundle.

The newsletter bundle is just the two games. Scroll up a bit.

Another code for the paradox classics bundle. At 85% off the base price it's a solid deal... if you don't already own most of the titles. Remove the strategy from the code below by January 1.

The paradox bundle pack would be nice if it included Europa Universalis III: Collection Upgrade. Could it be that paradox themeselves don´t know or forgot that Europa Universalis III: Complete is actually very incomplete?
