My feedback in the short time of playing the third session and only getting to about level 8 while playing off and on, it's a mixed bag. Good and bad, but expected.
I'm enjoying the more quests and fresh start, I like some additions here and there.
Private Mines being visible to everyone? Haven't seen it in practice, but the "on paper" sound of it is prettttty bad. Wasting thousands of caps to allow everyone to waddle over and poke through your stuff? Who'd do that? I wouldn't. I rather grab a sledge and head to a PVP mine. I really suggest rolling this back. The main reason people bought mines because it offered a safe way to get higher quality resources.
No Drop. Mixed reception both publicly and personal. I'm a veteran here, but not anyone note-worthy, just a random shmuck, so I'll give my random shmuck 2-cents. It has goods and bad. The good is it does allows people to be less cowardly since there's less risk involved. The downside is, because it becomes more casual, it loses a lot of the charm. A lot of charm. when I was new, the compulsive need to hide every 10mm and leather jacket was both exciting and terrifying. Kept me interested and gave the game a charming feel. The rage of losing my stuff certainly existed, but it never had me rage quit, just be a coward.
If you ever do roll back the no drop, PLEASE roll back the metal/gunpowder/alloy resource requirements. Having to add junk to everything is extremely tedious. Right now, it's okay because no drop. But if you bring back drop, remove roll back those resource requirements.
Other than those, I'm enjoying it, so far.
