This question already has an answer here:
I have bought a game, but a member of my family couldn't because of $$ and I was thinking if I can do this:
- Add his/her computer to the list of family share of steam to let him/her see and play my games (I already have done that).
- Block steam (and possibly the game too) in my computer with the firewall to go offline.
- Disconnect internet (if 2 doesn't work).
- Start the game in both computers (one online and one offline (the offline will be me)).
Before this, I could actually let him/her play my games when I don't play them, and going offline apparently don't block my games.
If I do this, do he/she could play it? (I don't care to go offline or lose achievements, but I care if I could get banned if I do this).
Also, he/she'll buy it, but meanwhile I was thinking if I can do this.
I have read this answer and apparently it can be done, but I want to know if this is risky.
