So now that I have finished Far Harbor and have completed all the other DLCs for Fallout 4, I can safely say that I have felt this season pass so far is not all that impressive and is very very likely to go down as the weakest DLC packs for the Fallout games and I am someone who got the season pass for $30 and I still feel underwhelmed as for someone who payed $50, it really sucks.
I actually felt Automatron was decent enough, but rather short as I completed it all in one sitting, still it was about as long as Operation Anchorage.
Wasteland Workshop was fun, but it got old real quick.
Far Harbor was very good, BUT it was simply not worth the $25 price. Sure the island was big, but the content was comparable in length to Point Lookout, Old World Blues, Honest Hearts etc. Far Harbor (as I expected it would be) was really a $15 DLC priced as a $25 DLC. There simply was not enough content there to justify the price IMO.
One other thing that disappointed me about Far Harbor is that it didn't add enough to the weapon and armor crafting. I figured they would surely have given you a station that would enable you to make your own legendaries and/or add ballistic weave to any article of clothing. I realize that you can do these things with MODs, but those fuckheads at Bethesda decided to disable achievements and that makes MODs a no go.
So at this point there is still $20 worth of DLC left unaccounted for and as of right now, I am not expecting much. Maybe two more packs with a length similar to Automatron.
Rumor has it that the next DLC will be a Nuka Cola amusement park and two more wasteland workshop DLC packs.
The next two DLC packs need to be pretty good to justify the cost.
