I mostly install features that impact gameplay rather than appearance, although there are a handful of the latter as well.
Unfortunately due to its engine, Inquisition is nowhere near as modded as Skyrim (the game I came from), or even the two previous games in the DA series, there are still a few mods that have discovered to be handy for my second, third, sixth games. After I completed my first vanilla playthrough of Dragon Age: Inquisition, I started looking into mods to mix things up, speed it up and add new things.
