You want to race against other players online - but, like, not an actual racing game with cars and stuff? Check out ReRunners. It's a really cool, quirky 2D speed-run platformer, but you're racing against your fellow humans.
The controls are tight, the presentation is brilliantly offbeat, and the whole competitive angle is brilliantly executed. ReRunners crosses a fair few genre boundaries, but what's remarkable is that it masters them all.
Here's another colourful, accessible multiplayer racer. SUP Multiplayer Racing might involve cars, but there's no cornering required - just a simple lane-switching mechanic, as you dash from left to right as quickly as possible.
There's a pleasing amount of argy bargy to its races, as you shunt and block your opponent en route to the finishing line. This is a multiplayer racing game that anyone can play and enjoy.
Sonic Forces is a multiplayer autorunning platform-racer, but it switches things to a 3D third-person perspective that's not too dissimilar to Wind Rider.
Of course, the colourful world and chunky 3D graphics here are way, way better. This is a Sega game, for crying out loud! But Sonic Forces also plays a lot better than Voodoo's game, with pacy loop-de-looping gameplay and entertaining power-ups.
If it's the whole 'flying through hoops' thing that you love about Wind Rider - and who can blame you? - then check out a little game called Ava Airborne.
It's a highly polished 2D autorunner in the Alto's Odyssey vein, but with an aerial twist. Guide your little hang gliding heroine through a series of go-faster hoops and other momentum-sustaining gizmos.
