Indeed, in our opinion, the sheer quality of workmanship in the visuals makes this game stand up better than its successor. It's powered by the Hedgehog Engine and offers visuals that still hold up beautifully even in 2018. Unlike those 30fps efforts though, the PC version allows for smooth 60fps gameplay and higher resolutions. Sonic Generations was released on PC back in 2011, a few weeks after the console versions.
The game has aged remarkably well, has exceptional modding support and runs well and looks wonderful at full 4K on GTX 970-level hardware.
Sonic Forces was a disappointment, a real shame bearing in mind just how good Sonic Generations was - especially on PC. It goes without saying that Sonic Mania is something truly special, a brilliant return to classic 2D platforming for the franchise - but on the 3D side of things, Sega came up short. 2017 could so easily have been the Year of the Hedgehog thanks to the arrival of two high-profile Sonic releases.
