After getting tired of creating and re-creating "Favorites" in my Web browsers and/or generally overpopulating them and making things messy to the point of poor usability over the years, a while back I began collecting videogame and computer store links - which I've been posting on the classic Armchair Arcade already - and system-specific links - which I have yet to post anywhere. The "store" links still need to be categorized, while the system-specific links still need to be fleshed out (to put both mildly). However, I thought I would share as-is for now in case anyone was interested in clicking around in their raw states. At some point, as I'm able to expand these into what I want, I suspect they'll be incredibly useful and perhaps I can do something more imaginative with them.
