They won't give you the game with 3 years of content on day 1, you need to learn.
Around 80 activities, not story missions.
That counts as a whole range of different activities including those story missions.
No one here has said that should be the case. Just that it should be significantly more than the small amount present in D1 at launch - which was one of its main issues. People assumed they would avoid making that mistake again.
Obviously it was never gonna be equal to D1 after 3 years of updates.
