I am also wondering if I will need to install a fan forced air vent
system?
Assuming my correcting the soffit vents does not solve the problem.

The condensation is so bad it forms puddles on the ground in the
spring.
And the garage floor does not slope to a drain. I really think the
garage was an old house at one point in time.
This really stinks in the winter with snow. I kept a large squeegee
in the garage last winter to push the melted snow out.

So I am set on standard 1/2" drywall for the entire garage.

Improving the ventilation is to correct the condensation issues.
Water is for a sink and brewing beer (there is an existing drain the
garage floor - looks like an old toliet drain (from the 1940's)
Heater is to heat the garage - while I brew beer or keep wife's car
toasty
Wood burner is to boil water
Attic is for storing X-mas crap
Attic has a window
Attic has proper ridge vent (new roof)
Attic has old improper soffit vents (from 1940's)
Attic has a pull down stairs for access
Attic has no floor!
Garage is 75 feet away from house - separated by driveway.

Wow, a dedicated beer brewing house! *I'm jealous.

Reading between the lines what you described (except for the brewing)
was pretty much what I thought you meant, but I wasn't sure if you
were dancing around the issue because you were converting the garage
to an illegal rental. *It happens.

If the attic has no floor you're good to go with 1/2" drywall.
