Leviathyn.com | I think the idea behind this DLC is awesome. In RPGs, especially the Elder Scrolls series, I really get into the whole homestead idea. It’s nice to have a place for your character to store loot with accessible tools like crafting benches or enchanting tables. I like the added roleplaying dimension of having followers and spouses staying with you at your house. I know that many players don’t care about the housing part of Skyrim, and care even less about DLC that allows more customization.
this is how pc has always been
a big FU@K YOU to bethesda and your horse armor, you ruined gaming forever
DayZ boosted Arma2 sales (and people bought the Arma2 DLC too because it was required for DayZ)
HalfLife had CounterStrike and TeamFortress (and many more)
Stalker, which was initially a bit flawed, become amazing with the user-created mods.
... that, and Bethesda's DLC sales haven't been that bad on PC.
So sales of the DLC won't really suffer that much. What does suffer are the sales of a sequel if it is released quickly. Hard to release a shooter annually when your playerbase isn't bored with the previous installment.
