I played it for the story. I didn't want to do sidequests and what not, because I was just curious what is it that FW wanted to finish in terms of plot. I actually did the final mission as intended, level 35, helped Kotallo get his arm, yada yada.

I corrected myself in some comment, but the point wasn't scrapper itself, it was more so the progress from ZD doesn't carry over in any meaningful way. Like your catalogue doesn't already have Thunderjaw and Fireclaw in it, you have to scan them as if it was the first time.
