I planned for an all disk install so I could stay at 1.67 on my new laptop. I got 5 discs in and couldn't get it to complete installation bc of a small scratch. So I ended up just doing the digital download for all ep's and sp's.
I only needed internet for install. When I run my game I put my laptop in airplane mode. Origin will pop up and ask for your password. You put it in, the launcher opens, and you start your game. I think the very first time there may be a message about being offline but that's it, no internet needed.
