To be fair even high end 3d printers often print out parts that look like garbage without a lot of finish work. I've got to imagine those fins would have been a nightmare to clean up.
But yeah, if it's crowdfunded then that means Atari isn't willing to foot the bill, nor are these crappy retro shovelware companies like at@games. In other words it's a horrible business decision, which means nobody is going to make games for it. (Not that I thought they would even when I thought Atari was doing it.)
