I don't really miss the physical copies but rather the manuals that used to come with them. As a kid who grew up playing mostly flight sims, getting a nice spiral bound manual in Jane's F-15 or Falcon 3 was amazing. The Mechwarrior 2 manual holds a special place in my heart. Back then, the first thing I would do was read the manual on the car ride back home. Nowadays publishers just don't publish manuals anymore or simply release it in a pdf and that really takes away the enjoyment of owning the physical copy.
