Can I transfer Rainbow six siege from the console to the PC? I put a lot of game time and money into it and would like to be able to play on the PC one day. Do I have to buy a new one?
Yes you have to. You can then log in to the PC with your account data
Yes you have to, unless you have it via Game Pass.
In a nutshell: You have to buy the game again on the PC and you can also play net with the console account on the PC
