I posted this on r/Starfield and decided to post it here as well for spreading the good news.
From the Beta and no mods I started a new toon and got to level 62. Then played my old superpowered 200+ lvl. Everything MAX (extreme) difficulty. Here is what I found.
Things that were completely useless or almost useless before THAT NOW MATTER:
-Food (stay fed to get a buff or malnourished get a debuff)
-Drink (stay hydrated to get a buff, or dehydrated to get a debuff)
-Aid items (bandages, etc.)
-Kitchens (to find food/drink)
-Previous useless chests and containers (to find aid/food/drink)
-Doctors and medical shops (to remove injuries or afflictions)
-Spacesuits (need resistances now)
-Spacesuit modifications (above)
-Companions in combat (harder enemies)
-Companions as mules (everything weighs)
-Flanking enemies (harder enemies)
-Ammo conservation (ammo weight)
-Environmental Conditioning Skill (resist planetary hazards)
-Nutrition Skill (amplifies food/aid)
-Cellular Regeneration Skill (heal combat wounds)
-Decontamination Skill (above)
-Commerce Skill (things more expensive, vendors less money, need for shipbuilding)
-Gastronomy skill (food)
-Leadership Skill (combat)
-Ship Command Skill (Space combat)
-Xenosociology (probably good vs hard aliens, I have not tested this)
-POIs in any planet that have hazardous environment (you can go to a civilian outpost to regen your suit environmental protection)
Thanks Bethesda for making things matter (shoulda been from launch). Feels like 95% of the things in the game matter now. The last 5% of things that dont matter are the ones related to the [cut] fuel usage mechanic and outposts.
Have fun with the update!!
Do we have a time of release?
