I don't think I should be forced to pay extra for what I think should have been included out of the box.
I hope you are joking :blink:
No, why? It takes time to add features, tweak them correctly, make it look good and perform good. And time is money.
The more money they get the more they can focus on certain things.
The expected DLC is quests and locations and such. Things that modders do as well. Graphics is very comparable here. Modders can do it as well (although not as easy, as modders need to "hack" the game).
So if normal DLCs are quests and locations and such, which are things that take time and that modders can do themselves, and that graphics is also something that modders can do themselves, but takes time (and is harder for modders even), then how would it be a joke to ask for a graphics DLC?
You might as well say that all quests and locations from DLCs should be included out of the box.
