There must be a more expensive DLC incoming because the Deluxe version was going for $25 more on (Canadian) steam and each DLC is going for $5.5. It would mean the Deluxe people lost money (-$3) if the next two DLCs are the same price. I'm glad too I didn't get it. Frankly I was torn until I saw the last few dev streams before the game was out and thought that the game had some issues that no DLC will make it replayable for a while, by then it'll be on a decent sale (I think it was the AI battle they streamed that made me think this way). Firaxis are free to package and price their content however they wish and same for us I'm sure different people are valuing the content differently. For me though, new civs is all I care about as they are the biggest game-changing feature in my opinion. So when the Deluxe version was going for ~30% more than the standard version, I would expect to see ~5 new civilizations in the first four DLCs. That means each DLC should at minimum introduce 1 new civ, in my view, to make it worth the money to me. Otherwise it would have to include a really good amount of city states and maps/scenarios not just a few.
