I’ve done two full playthroughs of the game (plus dlc), one on the standard difficulty and one on hard. I can confirm that many of the game’s systems are rendered unnecessary by the easier difficulty. I really enjoyed my second playthrough and would definitely recommend.

However, if you don’t think you’ll enjoy that (having to plan and work for every advantage to be able to succeed) I would wholeheartedly endorse the easier levels. The story and quest design alone are worth the price of admission! Side quests in this game make many other games main story pale in comparison.
