Allen Roush reviews the 3.05 version of Hearts of Iron 3, with both expansions.
Excerpt: "There are some limitations on how radically you can change the world. Due to the short time span (1936-1948) that the game allows you to continue into, you do not get to see the fruits of your labor. Countries will realistically join alliances the way they did in World War II; for example, there will be no Nazi-aligned United States. Most games will turn out very similarly. Almost 100% of the time, Germany will lose WW2 to all of the Allies in nearly the same way as it happened in real life. In fact, it is nearly impossible to win WW2 as Germany unless you can prevent the Soviet Union from declaring war on you as you try to invade the United Kingdom. Some would claim that this is realism, but this realism element can turn off many potential players."
