Huh, I'm surprised to hear you think it's useless since you're the one who decided to make it a two-slot item :3 I mean, I agree, but I'm hardly an expert.
Ha, well remember that not all parts are meant to be used by the player, too! That's what I mean by fluff.
You will find some parts that are outright worse than others, because all robots in the world are composed of parts from the same large set, and all are interchangeable with your own parts, so inevitably there will some that they need/want that you don't.
Of course, there are many more factors involved here--some players
will find interesting uses for some parts that other players completely ignore.
I do try to design parts so that as many as possible are useful to you in some way, even if under narrower circumstances. In a few cases I haven't found enough of a reason to use a few parts, but the lack of evidence is not grounds for complete removal, especially not when other robots can logically be equipped with them for fun. It adds flavor!
Maybe a utility that boosted matter reclamation from parts getting blown off of you would be actually useful to a kinetic/explosive combat build. Possibly, since the part's being blown off of you when it happens, strew the matter about on the floor, making it only super effective with a tractor beam also.
That could be a good one, yes. Maybe even a possibility for a revamped more useful version of the Field Recycling Unit! I'd like to say that I could just add this as a secondary feature for it, but then it would also be eating your damaged inventory items at the same time...
Aside: do footprint analyzers stack?
Any utility with a stacking effect will indicate <stacks>. If not then it only takes the maximum value. (So in this case, no.)
