Commodities of Martian Rails: Neural Jacks

Martian Rails (2009), the crayon board game manufactured by Mayfair Games about railroading on the Red Planet in which players build tracks and haul freight in sleek trains with names like Spirit, Tweel and Viking, has a long list of cool commodities that players can transport to generate revenue for their rail companies. For example:

Neural Jacks – Implantable devices that allow a human/computer interface. This is a direct mental link to the cyberspace, auxiliary memory, peripheral devices, or remote-control Waldos.
