Welcome Marco. Nice to see a collector of a "different" caliber on here. Not many I know collect "only" handhelds. Is that all you collect? Any "special" editions of handheld games or systems? The handheld that fascinated me the most, besides the absurdly popular Gameboy, was the NeoGeo and it's "vivid" style games. I still am captivated by the visual art of NeoGeo games. The unique and artistic visual style of the games was so dynamic compared to other handheld systems.
