There are more than 50 quests unless you're getting creative with how you count. There are over a dozen in each major faction, and those ones are mostly okay, but the ones I really take issue with are the nothing quests that aren't part of any faction; the ones that basically just have you go to a location and then report back. Those are awful. There should be zero quests in there that the quest designers themselves aren't excited about. Even the bounties that you pick up for a given faction that have you go to a place and kill an enemy mob should be more exciting than what I've already described in this sentence.

Starfield has more quests than Skyrim (both somewhere around 200 or so quests). Morrowind definitely felt like it was twice as much as those.
