7) Dishonored
You may have missed some of it during all that throat slitting and rat transforming, but there’s an interesting story about politics in the pair of Dishonored games. Of course, Arkane doesn’t entirely want you to get caught up in that, they’re more interested in showing how self guilt drives a person to do anything to reclaim something of great personal value.
Should there be any musical to pull from inspiration, the best candidate should be Victor Hugo’s Les Misérables. Both of Arkane’s stealth titles have featured attempts to remove Emily Kaldwin and Corvo Attano from power, and both games have played around with the idea of political revolutions to some degree or another, thanks to the different endings they each possess. While not an entirely 1:1 comparison, Corvo does want to redeem himself through his daughter Emily, not unlike Les Mis’ Jean Valjean. In the 15 years between the two games, that dynamic likely hasn’t gone away, and it would be interesting to see the two travel that path as he starts training his daughter in the way of taking lives.
Dishonored is partially inspired by 19th century London, from the music to the architecture. Dunwall is a messy city that, in the time between the two games, was likely home to some kind of uprising or two that didn’t end well. When combining that in with the fact that the incredibly creepy Outsider is always watching Attano and Kaldwin, how could that not be a musical?
