I bought both Din's Curse and the expansion during the intro sale, after having briefly played the demo (which includes Demon War content). I decided I'd play the base game for a while before adding the expansion (which I still haven't installed). I have already noticed several features, options, and quest types which were present in the demo, but which aren't in the base game -- or, in the case of quest types/NPC actions, which I simply haven't run across yet. That got me wondering...does anybody know of a fairly comprehensive list of things added/changed/removed in the expansion? Since I already own it, I ask merely out of curiosity (also the reason this is a normal post, rather than a "question / problem").

There's a feature list on the dev's site:
http://www.soldak.com/Dins-Curse/Demon-War.html

It's a bit vague, but if you want something more specific than that you might have to search around a bit more.

I can't really help much more than that because I've played with the expansion so long don't remember what wasn't there pre-expansion.

The demo does have the expansion features.

Yeah, I think I had already come across that when deciding whether I should buy the expansion with the game, or wishlist it and wait for another sale. (Obviously, I bought it. :) ) The linked page contains a little more info than the GOG store game page's bulleted features list, but aside from the mention of the additional class and monsters (which would've been the easiest additions to figure out), it's all, as you mentioned, rather vague. I was hoping someone -- perhaps even a dev -- would have posted a list of concrete additions/alterations somewhere by now.

Thanks anyway. :)
