thadian, I think your analogy is very incorrect and way off-base. Every software product can be improved upon with time and resources, but many have not while Civ4 and Civ5 did dedicate the resources to do so. I would easily and defiantly say that the initial releases of Civ4 and Civ5 were emminently and completely playable (which you cannot say for a lot of software releases) for many people, while Civ3 was not. Despite the workings of such pieces upon release, they were all there and every non-patches since then have been optional bonuses.
Civ5 does not have the luxury of EA, Bethesda or R* where consoles can generate 90% of the revenues. We should be lucky that strategy games for the PC is still a viable market, however they have to keep the revenues flowing. The alternative would not to have a PC release which is what we have seen in a lot of titles in the past several years.
I see his point as far as the fact that the vanilla games were missing much content. Then the customer has to pay money for each new expansion with added content, that pretty much we knew would be forth coming, because it existed in the previous game.
So he is saying they squeezed money out of the customers, which is true. But that truly is the business world these days. Sell your product in stages. In this case a civ game has three. From a corporate POV, they realize consumers will buy the vanilla version, then they keep them in anticipation until they can stand it no longer. While thats going on they wet the consumers appetite with DLCs (a new marketing strategy based on steam). Then finally they spring a new expansion on them with content we know they will be begging for that existed in the prior civ title CiIV.
Religion/espionage, a few new things to bolster the game and catch as much interest as possible.
During the market strategy for CiV prior to release, firaxis stated that they are making a simpler user friendly game (they posted a video showing new features of the game etc, and that they wanted to draw in new players), to draw in a new generation of civ players.
The business strategy is fairly clear. Marketing switches target groups, intially it corners new and old players alike, especially new, because of a simple learning curve needed to play, an easier vanilla version of the game. Then they switch targeting to the traditional civ gamers, who have playing these games a very long time. However, now the new vanilla players who are quite used to CiV by now are very curious about the expansion. Even though many have misgivings about adding content to this new game they love. Curiosity and anticipation of consumers equals sales. It is really quite genius. This is how I see it. This is capitalism at its finest.
I do not think it is necessarily wrong, as long as I can use what I paid for already. I bought all the DLCs, and I should be able to at least use DLC civs, if not civs and scenarios, which would be far better, with the new expansion pack. If this was not the case I would feel cheated, do you see what I mean?
