Hello, I plan to buy TSW for a PC without internet connection. Is it possible to install and play it offline? Thanks in advance for your answer.
Installing it digitally will require an internet connection. You can purchase a physical copy to download without a connection but any future updates will require an internet connection to obtain. As far as playing the game, you can do that entirely offline if you aren't concerned with the DTG live stuff such as Mastery and community challenges
Another way of doing it would be to install Steam and TSW on a PC that is connected to the internet, it doesn't matter at all if TSW isn't playable on that PC due to low specs etc. Do a Steam Backup of TSW on the online PC to an external hard drive and then do a Steam Restore on the offline PC. I've found the backup / restore method to work best with Steam rather than copying the files directly.
