From my understanding the $35 simply gives you early access. So you either pay $35 + $60 for the game and early access or $35 for early access if you have game pass.

For me, it's steep. As hyped as I am for the game, I'll get it on regular release with game pass and binge it the following weekend. That early access weekend is the first full weekend of college football and labor day so I'll have plenty to keep me busy.
