The Blood of Dawnwalker is a game by Rebel Wolves studio, founded by CD Projekt RED veterans. Previously, the authors stated that it would take about 40 hours to complete, although reviewers got completely different results.
The final credits were seen in about 15 hours. During this time, the main story quests were completed, a significant part of the side content, fast travel points were unlocked, legendary equipment was obtained, and most of the map was explored. However, a full playthrough with platinum and all endings takes about 40 hours.
The duration is affected by the in-game time limit and various simplifications. The game allocates a certain number of days to achieve the main goal, but with active play, the story can be completed with plenty of time to spare.
For players with limited free time, this format will be a plus. For those who expect a huge open-world RPG, the duration may seem modest.
