I'm immersed in this documentary / game collection. Even the apparently most simple of the games deserve hidden strategies. For example, the old Commodore VIC 20 GridRunner version, seems impossible at first for difficulty. But if you are a REAL passionate you explore the game manual (present for all games in this wonderful product), and you discover that the horizontal firing pod is less pericolous than the vertical one, and using this info you start to lose less life!
Just an example of great playability if you go deep with Jeff Minter games. How is selling? I'm hoping real players and videogame history enthusiasts appreciate this gem.
