Where they diverge is in what they consider ethical and what they consider borderline; they are not judgmental towards people who disagree with them, they respect everyone’s personal choice, but won’t condone it. The issues I’m referring to is the stance on using emulators and ROMS, which are legally grey at best, or console clones as opposed to vintage original consoles.
It’s a very vibrant scene filled with passionate and friendly people, some of whom have developed homebrewed games for consoles which production has stopped over a quarter of a century ago, and others have created programs to emulate these old consoles and let people play the games on newer devices.
Personally, I only care about playing games; I don’t have an unconditional love for original cartridges and authentic consoles, but I completely understand people who like these physical objects, and have nothing but affection for them and the way they live their hobby.
However, I have to mention that except for very few lucky finds at garage sales, gathering a collection of authentic game memorabilia can be very expensive for the casual retro gaming enthusiast and that cheaper alternatives deliver a much better value for your hard-earned coins.
