I haven't played since V25.
Low HP enemies at the start makes a massive improvement.
The updates telling me the gangs have increased in level and built facilities promotes a good sense of urgency.
Breaking down ammo is most welcome.
Being able to craft ammo is Awesome.
Increased supplies of stuff at the shop is great (it's not excessive, but a noticeable improvement over the constant scrounging for armour components in V25).
