I've been playing since Dec 21st, 2017 and I've got more than 2500 hours logged.
I LOVE THE NEW CHANGES! Managing ships with trade and mining loops before was just annoying. I spent most of my time manually trading to build up income, as well as exploring. Now? Exploring is almost too easy - my current gameI have over 7500 sectors explored, thanks to my explorer ships and captains (almost triple that of older games). For me, a game didn't really start until I had a rare or better trading system. Now, it's find a merchant captain and send them off to make $$$. That means more time I can spend looking for new captains, checking out station missions, and other higher level stuff. I'm going to say a happy goodbye to order looping. It was wonky to set up and it caused performance issues. Missions are great, although expeditions feel kind of... underwhelming, honestly. Expeditions should have effects and events that only happen on an expedition - you get more items with salvage, more credits with trade, etc.
I used to make ships for specific tasks like mining and trading, but they'd often sit idle. Now, every ship I have is almost always working, to the point where I feel guilty if they're not off on a mission. Captain traits are interesting, but they seem a bit limited - there's definitely room for more. There's also a great opportunity to have captains gain abilities as they level, like a maybe a daredevil getting a 5% bonus to a specific type of damage at level 3, 10% at level 5, etc. My fleet is definitely active, and the shield module changes actually resulted in my ships being outfitted and ending up wth more shields than I'd normally run. I've also made a 15-slot ship for the first time ever because of 2.0 and it's amaaaaazing!
Fighters are even tougher than prior to 2.0 - being able to fire from extended ranges was their biggest strength before, now it's massive HP per fighter. I have fighters with over 1250 HP each, and they're still wrecking everything they face, only faster now with the range boost ability. It's like commanding a swarm of space piranhas! Nothing I've faced so far uses anti-fighter cannons, which means I've destroyed entire sectors and not lost a single ship (that's bad - I should be taking losses).
Trade has gone from a bit of a pain to "I have SO MUCH STUFFFFF". Procure missions are so good, you can't even imagine how happy I am to have them. You know what would be even better? Making a way to have a turret part list populate a procure mission's item list - there's a nudge, nudge suggestion for you from me 😉 And having smuggler captains being able to sell stolen goods without having to find and visit a smuggler? YES PLEASE!
The changes you've made for 2.0 are really, really good. Some people are always going to be unhappy with any kind of change, and there's nothing you can do to appease them. Just keep going and make the game even better!
