but no other game encourages you to spend tens of hours on tedious pointing and clicking just to throw it away
I don't really understand the NG+ complaints. The game warns several times in several ways you before you do it, and it is absolutely not necessary to enjoy the game. And people who know the reasons you'd want to NG+ because they read spoilers? They ALSO know that they're going to lose the previous playthrough well before they've gotten too deep into outpost design.
The most common Bethesda play pattern is to reach a point your'e so powerful you're "just done", so you go beat the game. You take a break, and come back to NG. The number of people who maintain all the FO4 settlements for hundreds of hours are quite rare. NG+ exists to give people of that most common play pattern the option to start over again and extra content they'll enjoy.
Starfield is technically bigger than Skyrim before accounting for NG+. So why punish them for a new feature that rewards what most gamers want to do?
I feel like this is a "this is why we can't have nice things" scenario. I have been wanting a fun NG+ mechanism in a Bethesda game for 15-20 years. I hate saying goodbye to my character, but I love rising through the ranks and completing major story quests in different ways.
