I think this is probably a very niche, yet very wanted request, I personally think that it would bring joy to the community, Being able to access, for example, Your PS5 DTG account on a PC version of TSW, I'm not talking about transferring the GAME itself, I'm more referring to the DLCS, I think it is hated by many that you have to rebuy such valued DLC's just to play on a new device, and I think this feature being added would frankly benefit BOTH parties here.
A pc and a console are 2 completely different machines. Console code and pc code is very different. It just doesn't work. Even the hardware and software is very different. No other games can make this happen so tsw can't either. Even if in an alternate world it would work, the platforms would hate it if they lost money by allowing free transfers. Remember they are all business after all
I can’t think of any multi platform game where owning it or DLC on one format, gives you it free of charge on the other - philanthropic though the idea might be. Just wait for a sale, as I recently did to grab NTP for my PS5 version of the game (unless you’re one of the poor sods on Xbox/MS Store).
If you buy dlc on PS your buying it from Sony, Xbox your buying from Microsoft. If either company had their way, tsw would be an exclusive for one or the other. I doubt they would ever allow you to buy the game on one platform and be able to get it free on the other. Same goes for pc, steam and epic are separate companies, if you by from steam they make commission on the sale while epic does not. So epic games would have to give you the game for free and vice versa. Even when you buy direct from dtg, you have to chose a platform to play it on. Although if you own a Xbox, you can use your Xbox account and games on the PC, as long as you are using Microsoft windows. Because Microsoft owns both platforms.
