I'm really not sure what people were expecting for $25. Sure, I can name a handful of games with more new content for less. But on the other hand there are thousands of games that charged more than that for much less content. And for the most part those games weren't at their core as good as Fallout.
Would I have liked my season pass to contain more content... sure. But that's hardly surprising... I ALWAYS DO. At least they didn't pull that crap of multiple "seasons" of season passes. Or any content that the season pass does not actually get you. With FO4 it was just $25, boom you get all we're making. And so far, with what many... many other games seem to think their expanded content is worth... I think I've gotten my $25 worth.
And if they come back and offer some more DLC past the announced "end" of the season pass or a "season 2 pass" or something like that... yes I'll be angry. But I ALWAYS WOULD BE. That wouldn't change $25 being great value for the 6 DLC packs we are getting for FO 4. Hell, getting Far Harbor and Nuka World (even if it turns out to be only 1/2 as big as Far Harbor) for $25 is fairly good value. Adding on $20 worth of workshop DLC on top... I don't really get the whining.
Now of course Bethesda has announced that PC players get Skyrim Remastered for free as an update. That's nice of them and I really appreciate it. They also said that to get the free upgrade someone has to have purchased the "legendary" edition or has to own ALL of the DLC's. Now, I understand its for maximum compatibility and I get the reason for it. But... all the people who skipped Hearthfire because "I only buyz the STORY DLCs, I don't wanna the workshop stuffz..." I just love the idea of Bethesda saying to them "well, tough. if you want the new stuff ya gotta pony up."
