I paid for an expanaion ala Left Behind as had been advertised/promised with a price to reflect that (£10), instead I am getting a full blown standalone release on the scale and with the lenght of a new entry - I'd consider that a steal.
When could you ever buy Lost Legacy for a tenner?
Because ND chose to honour the original price, which was a nice gesture on their part.
Nice gesture? If they did not honor the price they would have to:
1) Create another piece of single player DLC in it's place
2) Refund all season pass and/or Digital deluxe edition holders a portion or all of the price of their respective purchases.
I'm not sure where exactly the cut-off is but:
Physical release
Doesn't require original game
Self contained story
Full length game
$40 price point
Add to this the fact that they had to hire actors and record a shitload of MoCap. All of these combined make it a spin-off. Meaty DLC is more along the lines of Blood and Wine. And just to reiterate, it is not available with the season pass. It was available with the season pass with when it was a different product. ND were cool enough to honour their offer for DLC. A lesser dev could have just kept to the original plan or chopped in in half and charged season pass holders for the rest of it.
There is no more season pass for UC4, you can no longer purchase it. When it was, Lost legacy was definitely a part of the package.
Interesting that you mention CDPR, because if they were a lesser dev they could have said "we've increased the scope of Blood and Wine so we're going to spin it off and raise the price while also eliminating a way for you to purchase the previously available season pass at a lower price........."
