It is one thing to churn out quick DLC content post release of a game, but it is sickening to see companies not even attempt to hide the fact they are excluding content months in advance just to make some extra cash at the consumer's expense.
They're not excluding!
In a game like Skyrim a billion ideas come up. Some of those ideas get cut because they suck. Other ideas get cut because they simply don't have enough time or money. With DLC, they can revisit those ideas at a later date. So, when sitting in a project meeting and realizing they need to take something out, rather than going through the heart-wrenching process of deciding what audiences never need to see they can instead just say "well, we'll add this later on."
It's not "excluding," it's giving you something that you wouldn't have seen otherwise. I swear, it's like some of you think that these companies either have infinite budgets and infinite time or you think they're exactly perfect with their time planning and never have to drop features and content as they move closer to release.
