The Danish Navy had three large two-deckers of about this size at that time (the Chr VII of 90, Neptunus and Waldemar of 80, plus two oversized 74s, Danmark and Norge), with 74- and 64- gun ships making up the rest of the battlefleet.
Limiting Denmark at least to building no three-deckers makes perfect sense in the game.
