What does a player do during a 15 real time minute or longer voyage from here to there? I played NMS, and the longest I was ever in a black hole (fastest way to go somewhere) was 2.5 minutes. In which case I went 3.5 thousand light years. Jesus, at my present age, I may not make it out of the confines of the bubble. LOL
In Elite you will learn to get used to the wait, or go back to NMS
For longer runs some players listen to music, some PC players with 2 screens chuck Netflix on and watch something.
The big risk is that you need to be in control of ship post jump to ensure you don't accelerate right into the star!
After a few hours of gameplay you wont even notice the transition!
