It's darker, it forces you to really make important choices, it grabs you and immerses you in the story.

They had to make a few changes to companions for that ? Big deal ! Don't you take a great scenario over a secondary gameplay content modification ?

4.0 brings fresh air on the game, tactical FPs are harder, storytelling is stronger than ever, customization is easier and the RPG aspects are better.

I'm old school and RPG doesn't mean Hardcore gameplay. It stands for immersion and that's what they brought with the last patch.
