I’ve just noticed there’s a sale in the PS4 UK store with lots of TSW2020 goodies with good discounts. Just downloading a couple of bargains now. I’ve pretty much got everything I want in TSW2020 now and am all set up for near full preserved collection experience once it’s all available.
Yeah, if it's already been preserved, I'm pretty sure it'll show up just like your other preserved DLC do. Edit: Sorry, I misread your post. I'm not certain it'll work if you don't have the TSW base game. Does it even let you buy TSW DLCs without owning the base game?
I don’t know if it would let you but if it does and you want to gamble with your cash and buy a DLC for a game you don’t own then go ahead. Come back and tell us what happened.
