Another great deal from Bundle Stars. I don't know about the rest but the Cossacks games (inc American Conquests) are easily worth it. They are the best RTS games I've played.
- Blitzkreig Anthology
- Blitzkreig 2 Anthology
- Z
- Cossacks: European Wars
- Cossacks: Art of War
- Cossacks: Back to War
- Cossacks: Campaign expansion (DLC)
- Earth 2140
- Earth 2150 Trilogy
- Earth 2160
- American Conquest
- American Conquest: Fight Back
- Cossacks II: Battle for Europe
- Cossacks II: Napoleonic Wars
Worth noting that there is a remake of the original Cossacks in development: http://www.cossacks3.com/
Not my cup of tea, but great price for 14 games.
