I'm just kinda' idly wondering here, but maybe there's room for something to do with salvaged mecha beyond stripping them for parts and/or selling them, at least in the sense of future consideration.
Some kind of junk guild/faction, or factions giving some sort of individual reward for bringing in certain machines. Perhaps trade ups of some sort; bring in three base buru-burus, get one (still salvage tagged) Heavyfoot. Bring in (5-10), get a custom machine. Stuff like that.
Just strikes me that, if 'cash' isn't the answer for the existence of (slash motivation to haul around) salvaged machines anymore, maybe there's room for something more dynamic. It would definitely make sense to get some sort of reputation if you regularly haul in salvaged machines, at least. I think, anyway. Part of me is suddenly pondering a scenario where a (villainous) character decides to make themselves a nice little throne/pyramid out of salvaged mecha heads (Perhaps with pilots still in them, heh...).
Anyway, I need to crack open this version. Been a bit since I sat down with GH for a while. So, generic praise for the continued work, Mistah H.
