Considering the time you actually "play" during the MSQ, without watching cutscenes, you only get about 10-11 hours of actualy gameplay (and most of that consists of running from one NPC to another)

Yesterday i got my other character through the 7.0 part of Dawtrail, skipped all the cutscenes and that was my final playtime result.



This is from when i started in Sharlayan until right after the credits, after defeating Eternal Queen.
There is also at least 1 hour of waiting for dungeons/trials included and i collected all the aether currents.
