Because there was nothing to do except building up for war and fighting in HoI3. It completly missed the diplomacy and even large parts of the economy that were important for WWII. And the politics were soooo bad. If they don´t improve those parts significantly, the game won´t be worth 40 € for me. Probably not even 10 if it ever goes on a sale. And don´t get me wrong. I really like the time it is set in. And i also (kinda) liked DH. But after looking at HoI3 i´m not sure if PDS will improve the game enough for it to be worth buying.
