I really like the new update, mid game makes a lot more sense now. Using those arc furnaces for scrap melting feels great, especially the glass, as it allows me to run one bf2 doing fresh glass while still having enough capacity to service the recycling plant. Both glass and steel production lines are great as they are now, but I hope they redo copper at some point though. Maybe add a toxic slurry output to the electrolyzer.
I'm about to start on lab 3s, so far I've been running an 8MW baseload wood power plant that supplies most of my water with the low pressure steam and 20MW worth of diesel generators. I'll be switching over to nuclear 1 so I can stop using all that oil for power, and upgrade it to mox as quickly as I can produce the construction parts for all the infrastructure.
