Speaking of ill-fated lines - anyone remember Mode:Lock?
It was a collab between Kotobukiya and Atelier Sai, featuring cheap-ass model kits of various mechs that were almost entirely made up of Lego Constraction-esque balljoints and compatible with Sai's BJPM system.

The whole line was kinda shit and probably the only worthwhile thing these days that came out of it were the Skygirls suits while everything else got vastly superior renditions these days.
