Can you still skip 5 seasons in SO6, I have tried it by holding shift as in SO5, but it doesn't seem to work on SO6, does anyone know? Thanks

Yes definitely works in SO6. I have used it for all my new games. Just to double check I started another new game just now and skipped 6 seasons fine. When you start a new game select Autorun for 1 season, then click the doorway to go into the next screen, which is the Legends. After selecting what you want to do with the legends, then hold the shift key and click the doorway again. Keep holding the shift key for 15-20 seconds or so. Should work fine.
