Daniel Lefkowitz, a longtime customer at 8 Bit & Up, likes the Golden Eye and Conker’s Bad Fur Day Nintendo 64 games just fine. But he has a special love: Elmo.

“It just cheers me up after a hard day,” said Lefkowitz, 27. “I get to go home and turn on my N64 and there’s my little guy, laughing and jumping around. It just comforts me.”

Even in the age of high definition, blocky 1990s Nintendo 64 video games thrive in a shadow market at places like 8 Bit & Up in the East Village. Lefkowitz is among a growing group of buyers spending big bucks to revel in the games of the past.
