When I get on the airplane with no internet connection, will I be able to launch those games. Sure that question has been asked before, have to do some looking around. Thanks again.
Honestly, I do not know... But you can test it: In Steam, go to "Steam", then "Go-offline" and see if you can still lauch your games. For sure, the games need to be up to date (beta opt-in don't count, I think...), but it should work... Well, if it does then your laptop will work in the airplane, if it does not, sorry.
