when SteelBook Hitman 2 comes out on PC
It already exists, you get a steelbook with the collectors edition.
I want a steel book with a disk
Well that doesn’t seem to be an option. There is a steelbook for PC, if it’s important that there is a dvd disc in the case. Then you can simply add it afterwards.
There is a good reason to why companies don’t do physical pc games anymore. A pc is useless without internet today, all pc gamers got access to internet and a lot of modern computers don’t even have a physical drive anymore.
