Good to know Kryo.
I'd advise that you play a couple random campaigns in Dread Lords and Dark Avatar before moving to Twilight of Arnor though. I just purchased the pack a few weeks ago and wanted to jump straight to Twilight of Arnor. At the same time, I like to see the improvements from expansions and mods in my games so I can see the differences/improvements and ultimately appreciate it that much more.
How do the story campaigns play out if you jump straight to TA and go through the DL and DA campaigns? Do they limit the tech tree and such to their respective games or does it adapt TA features into the old campaigns?
