Yeah and i do believe that the aes has got the longest lifespan of any console released as well, correct me if i'm wrong guy's but it's 1990-2004 and officially a 4th gen console...
The PC Engine technically received commercially published software across 11.5 years.
The Famicom library spans 12 years.
The Playstation 2 library spans 12.5 years.
The Sega Master System library spans 13 years.
The Sega Mega Drive library spans 14 years (1988 - 2002).
So the Neo Geo received commercial software about as long as any other console and other consoles released not long before or after came close.
It's impressive that any early consoles lasted longer than their generations, let alone spanning several.
