I dont think people should compare what was free with what you can pay for to judge the value of the DLC, its a separate thing, they added alot to the game for free, that they didnt really have to, but I guess they consider it things that should be in the core, and also made a DLC which you can pay for at the same time.
Things maybe they had hoped could be in at release but just couldnt make it, maybe. And now we have a DLC that expands the game, purely optional,. And said we will have £10 for that,
Is it worth £10, I dont know, probably not, when you think an entire game is only about 3 times that, but when is DLC that value, you could say that for every game.
For £35 total its a bargain, If they had halved the content and made 2 separate DLCs at a £5 each I think people would be thinking, great this is just what I get for $5 every where else, I think the deluxe edition was an extra £5 for an extra 5 objects, you pay £5 for basically a few skins in many games games if you want.
Imagine if they had patched day and night close to launch or even a month ago, and then released a content DLC like everyone else does a couple of month later, would this conversation still exist...
What was free is what CO believe should be considered the base game, while we also have an extra content DLC we can buy. First of many we hope as well as chucking in a bit of free stuff, maybe not so much for free next time cos some people believe that somehow makes the DLC worth less.
