I've sunk plenty of hours into the game, some of my takeaways:
The crafting system is nice, but mostly pointless. especially during the "second half" of the Slums part of the game, the weapons you find along the way are so much better than some enhanced wrench from 5 minutes ago. This slows down dramatically
where you actually find weapons that are worse than what you currently have, since you're approaching "maximum weapon level" territory.
Some parts of the game are bugged as hell. I, for example, am currently stuck at "1000 survivor exp below lvl 25" - the game thinks i am at max exp, so i'm not getting nor losing any when i die - yet i am not lvl 25.
also, the trophy for climbing 8000m is super glitched, ... i should have gotten that one ages ago.
Some of the sidequests are just super lame. Like "collect lighter fluid" "collect painkillers" - which are random pickups from stashes across the slums that you weren't able to find before getting the quest.
overall, it's still an amazing freeroam-fuck-around-while-listening-to-podcasts-or-watching-youtube-game.
