I stumbled upon Rick Brun's site recently (NESmaps.com) and spent hours pouring over every pixel. These are maps I would have seen in Nintendo Power as a kid or would have had to create on my own in my handy gamer notebook. I loved recalling the twists and turns of the games and wanted to recreate the adventure.
Recent travels introduced me to the beauty of transit maps. Most designers immediately see the talent in the London Underground design, and (living in DC) I grew up with Lance Wyman’s Metro map. Metro → Metroid, perfect!
