Civ IV had two expansions that probably went 30$ US for each on release? So that's like 65$ with tax for expansion content alone. Good for about 13 civ V civs. Let's assume additions come in the form of patches. If that's wishful thinking, lets say they put a 4-5 civ expansion with those added features. That's about 35$ worth of DLC. So that gives you about 6 more civs sold separately to equal $65, giving you ten civs + extra features. So they money works out somewhat. Keep in mind that if you buy these on release you are paying top dollar for them. You are probably going to be at least 100$'s into the game in a couple of years, with civs and possible expansions. Then again, we may not even get an expansion, but I also feel it is wishful thinking expecting to get all these new features for free in upcoming patches.
