12. Sonic The Hedgehog - Sonic Mania
Is there honestly a sadder example of one of the greats crashing and burning in such spectacular fashion as Sonic?
Perhaps the series could have been preserved if they'd stuck with Sega America's original plan to make him a trash-eating track star from Nebraska named Sonny (seriously, look it up).
One reason was graphical improvements in video games. Sonic just never managed to make the jump to 3D particularly successfully, but still jumped five thousand sharks in the process.
Sonic Adventure was uneven, 2006's Sonic the Hedgehog had him kiss a human woman, Sonic Boom: Rise of Lyric was a mess, and that's barely scratching the surface.
How do you fix a beloved franchise that is bombing so hard it can be heard around the world? First off, you hire a team comprised entirely of Sonic fans. Secondly, you take it back to its roots, and that's just what Pagoda West and Headcannon did.
Sonic Mania did what the series always did best: rapid, side-scrolling action that was colourful and, most importantly, fun. Even remixing classic Sonic levels. Sonic Mania is a testament to the fact that, just because things change with time, doesn't mean you have to.
Do what you do best.
