I just purchased Arcanum from GOG. 50% off was enough to get me. Before I jump in, I just want to know if there are any mods that I ought to get before going in. I've been playing Planescape for the first time with mods, and want to do the same with Arcanum. Can anyone point me in the right direction?

Just in case you have yet to start a new game (a full 11 days later) and you haven't already seen this, gog has a comprehensive list of mods that you probably should get: http://www.gog.com/en/forum/arcanum_of_steamworks_and_magick_obscura/must_have_arcanum_fan_patches_widescreen_and_more/page1

The high-res patch is a bit of a bummer compared to the ones for PS:T or Baldur's Gate, since it doesn't scale the UI.

Is this a Troika game? Or am I thinking of something else? If it is, then you're definitely going to need the "Hey, QA Guys, We're Tired of Doing Your Job" Mod that's standard for all Troika games. Yes, all three of them.
