I know classing consoles as “Retro” is a little lame, but I think it’s enough of a globally acknowledged category to be fitting.
I have been a gamer for years, and as such I learned on the retro consoles.
Master System
The Master System was my true love for years. Getting it for Christmas, it introduced me to some of the greatest games in existence: Alex Kidd in Miracle World, Sonic the Hedgehog, Operation Wolf. Without it’s influence, I probably wouldn’t be a gamer today. Damn you SEGA!
