Idea: show date of manufacture on ship IDs; can have it exclusively in the fleet/shop menu
Reason: helps players grasp which ships are old clunkers withstanding the test of time (like so many 212's) as opposed to newer models such as the Eagle.
Extras: amount of nuclear fuel depleted. Could work like mileage. Or, alternatively, time spent at operating temps, or time spent with the airlock experiencing a pressure differential (dive hours)
Affect on gameplay: none :) it's clear Koder doesn't intend for hull age to matter and that's working fine.
Easter eggs: Ships manufactured before a specific date...have an easter egg somehow, iunno. Maybe pre-class-3 ships. Or pre-Ganymede takeover. Dialogue option or something; whatever.
