When I first started working on games, I used high level frameworks that would give you a Camera that just kind of worked. But as I learned more and wanted t...
Perspective projection formulas are a walk in the park until you need to rotate things and compose rigid transformations, you better know how to build those quaternions and matrices ;)

You don’t need quaternions for affine transformations.
Does rotation not result in gimball lock without quaternions?
It sure does but quake1 and quake 2 happened on matrices and Euler angles so there’s a long way you can go before even thinking the letter q.
