Despite not actually being out yet, some players have already completed The Order 1866, and a selection of those that have completed the game have shared their experiences online. One player, who posted his entire playthrough online, managed to complete The Order 1866 in around five hours and a half.
The 5 hour playthrough followed the player as he completed the main story, whilst neglecting a lot of side missions and extra playable content. Going from this information, we can make a pretty accurate estimate that if you pick up The Order 1866, it's going to take you at least five and a half hours to complete, and that's if you skip everything you possibly can. It's also important to understand that the gamer in question managed to get through without dying a single time.
Despite only lasting five and a half hours, the player described that the story-driven singleplayer in The Order: 1866 felt like it lasted a lot longer. This could partially be down to the fact that the story in The Order: 1866 is expected to be a lot more engaging than the typical game.
Other players have reported that their experience of The Order 1866 has lasted a lot longer, with the typical completion time sitting between seven and nine hours. In fact, the first player to pick up the platinum trophy from The Order 1866 took around nine hours on his first playthrough.
With recent rumors of The Order 1866 only lasting 3 hours, it's great to see that the game actually has a lot more content in it, and I'd be happy to spend seven or eight hours completing the game in my own pace.
