Parvati really is a great character, it's a little bit of a shame that she is introduced immediately before heading out into the wilderness and killing lots of people, as I suspect most people will take her along because of it and it's quite at odds with her persona.
I was thinking on some possible roleplayed playthroughs, and hit on "board-aligned double agent" - with the objective of taking out the rival factions with minimum casualties. Spoilers for each faction:
- Edgewater
- Phineas
- MSI/Iconoclasts
- SubLight
- Groundbreaker
You can see why I've put Groundbreaker last - I think that might be the most horrible thing I've ever thought to do in a game
