Now this week I am currently on Day 68.
Acid, I haven't found a bottle since Day 28, but I have purchased 4 bottles of acid from the 5 various traders I visit.
The Sewing Kits, this has been one of those items that seem to be ready to jump into My loot. So far I have 23 sewing kits and already used 6 making pocket and Armor mods.
Wheels are very rare as well, which is driving one of My usual players batty. She rants each time We play at seeing hundreds of tires across the land, but can't find a single one still usable. Its Day 68 as I mentioned and We have 4 players. One motorcycle, One Minibike, and two bicycles. I will at least be creating one other motorcycle or possibly a 4x4 this weekend, as My friends get home and ready to play some 7D2D.
We discuss the argument points around the lack of an ability to create beakers as well. We think a beaker should be available much easier, since it is merely a glass container with graduated measurements for determining volume. Many of My friends that come to play with Me, argue that a carafe from a coffee machine should be an "apocalypse beaker" so they always say "Wouldn't it be great if the Coffee machine had a chance to loot a beaker", the counter-point that some of Us make, is that a coffee carafe is generally not made of sturdy enough glass to be considered a beaker.
So, I am making it through, but My gosh, I agree with Others that progression has been very slow in obtaining things We had become accustomed to finding/creating much earlier in previous versions of 7D2D. We didn't get a Chem Station created until Day 52 and with none available to use from any Trader POI, or other location, kept Us in the *chuckle* Stone Age much longer than We had been accustomed to. Overall, the world in A20 has seemed much harsher, but not unsurvivable. I've only died once in 68 Days, and that was on Day 2 when I was shocked to get caught in a Police Station POI and a Fat Cop came rushing out of one of the offices trapping me in the room with no exit , with only a Stone Spear and a pipe Shotgun with 4 shells.
So "surviving" is definitely do-able just more difficult.
