Sega is joining in on the nostalgia train, and this September will be releasing a mini Sega Genesis with 40 games and cost $80. There is a partial list over at Polygon, tho my only real concern is there is already a pretty substantial collection on the Xbox, Sony, and Switch. Many of the games in this mini already exist on there, so I am hard pressed to believe they will find 40 games warranting that price tag. It will be interesting to see tho, best wishes and may the gaming gods bring you glory.
Sega Genesis Mini

Although 40 games for 80$ price tag isn’t bad, you hit the nail on the head with most of these probably readily available on PS4, Xbox One and Switch.
Some of the ones already listed, Shining Force fot example, while I love it I already have on my PS4. Its going to he a hard sell if they have to many overlapping games
