Seems I was a bit wrong in my stats last time. I was 50% complete at 8 hours. However, I was pretty close to completing the story, with only a handful of missions available. Still, it took me over 12 hours in total before I completed it.
Thankfully, the ending mission was more lighthearted and less back-stabby than both Nico and Jonny’s plotlines. Even if it did turn out to be utterly ridiculous. Fun though.
