So if you played tsw 2 on console this whole time until you decided to go on pc, could you be able to connect your Console account to pc because, if you spent a lot of money on a dlc on your console you might have to spend it all over again on PC.
No. When you have played on your PlayStation you have brought the PlayStation version, to play on a PlayStation. To play on PC you would need to buy again on the Steam store (just like any other game sold on multiple platforms)
