Long time ago Sega made these Sonic games, which were innovate in a few ways: featuring full 360 degree ramps and fast scrolling speed, with main character, Sonic, acting like a pinball ball (they actually made sonic themed pinball game). The last proper Sonic game had to be Sonic Extreme for Sega Saturn, but back then Sega went nuts and killed the project, together with the Saturn itself.
Note the fish eye projection - game's main gimmick. For some reason nobody since have reused the concept, because nothing of it appears to be patented. And Sega themselves just killed the series with numerous shitty unplayable games, like Sonic 2006, which was even reviewed by AVGN: https://www.youtube.com/watch?v=Sr_rd6DpxM0
