You know, I have a theory;
At first I discounted the Babylon argument and hysteria on paying DSLs primerally because Babylon was part of the Digital Deluxe package and it is far worse to submit an exclusive civilization for free to standard games, Babylon was effectively a baseless civilization to perpetuate the notion. Now with the newest DSL, charging context that IS completely new, we now CAN run screaming into the night, stricken with horror.
Having said that, I also really don't understand why people hate the game. I find no real problems with the game at all, with a notable exception to the social policies, the idea of changing the civics to this particular system makes little to no sense. I personally will claim every civilization Firaxis puts into their pantheon, if for no other reason, I love to fully comprehend the implications of every civilization's trait and examine them in depth. Incidently, Mongolia is indeed a powerful military nation, Babylon is way too overpowering in science. Someone please update the Babylonian content in the Civilizations tab.
But to my theory; I have a slight suspicion there may well not be an expansion. So far, with the exception for Mongolia - which I suspect was a feeler to gauge the community - and patch updates, every new DSL has been tolled. The interesting thing is that each of these changed DSLs hold new gameplay options; Babylon, the 'Cradle of Civilization' maps, now this 'Spain, Inca and New World' package. All the updates were free and automatic - because they are designed to make better gameplay by fixing problems - but the new civs and maps cost money, all these are purely designed to add more choice and flavor into the game, not necessarily to improve it. I'll grant you that this the only the third DSL out, but this does strike me as something to watch over time when more new content comes out.
Ultimately, this can only ever be a theory until proven wrong - with the appearance of an expansion pack - or right - with the announcement of the next game - but a good litmus test for this is to watch CiV under a microscope, check every DSL as they come, I certainly will, and track the content and prices of each one.
