The credits are easy but to recollect all the mats again, unlock engineers and guardian stuff. It would be a nightmare...
It's actually not that bad. My main account is still lost in the Solitude Void, so I started a new one to check out the IntIniative. It took a week of casual play to earn enough to cobble together an A-rated scavenger ship, unlock 5 engineers, Max out what little they could do for me, and I'm now out at the Prospect Landing in a barely engineered DBS. I reck on it will take another week once the IntIniative is over (of casual play) to unlock the important engineers (Palin, Selene, Cheung, Didi, Broo, Zach, etc.) and I'm not fussed about speed collecting mats, I'll have plenty by the time I've unlocked more engineers to get a good start - add the experimentals and pin the blueprints. Knowledge... about credit earning, engineering, ships/weapons... makes it so much easier.
Having said that, don't leave PS4... once the stragglers get back from DW2 it'll pick up. I saw nine different cmdrs in about an hour near Prospect today.
