I hate to tell the naysayers this; but yes, retro titles are hot, and are NOT just a niche market. The PC version of Sonic Mania sold 100,000 units in 3 days, it's the number one title on the Nintendo Switch, and the 1# in the UK right now. Crash Bandicoot and Sonic are battling for the 1# position right now on the play station. Just this past month, the retro titles outsold most of the big AAA titles by a wide margin. the only two PS4 titles to beat Sonic Mania were Madden and Hellblade. This is actually happening.

These games are made on a smaller budget, and with a shorter development time. Could you imagine what would happen if Konami got the license back, and made an upgraded 2d sequel to turtles in time? Or even if somebody else made a TMNT retro arcade style beat em' up, and followed the Konami model faithfully, we could have a mega hit on our hands.
The retro game boom is not just a hipster niche market, these games are SELLING!
