As amazing as a sequel to Arcanum (or just a new game in the setting) will be, I highly doubt it'll pass the "modern standards" check.
Troika's games are much too obscure, for better or worse, otherwise people would be throwing a fit at how "problematic" their writing is and such. Looking at what Bloodlines 2 is shaping up as (and at Paradox's handling of the setting / ruleset), it's the most sanitized, inoffensive "dark" urban fantasy one can imagine.
It also seems like my rant was eaten by the forum spazzing out. Do Larian even care about the discussions here at this point, or has their attention shifted to the more "modern" platforms, and so the forum is mostly dead on a good day and very much dead otherwise?
