I picked up Descenders and Absolute Drift. Only tried the latter so far, but it's great fun. Feels like there's an extremely high skill ceiling to it that I am unlikely to reach. It only cost me £1 too!

I normally go for sim racers like Assetto Corsa and Automobilista, but I have a real soft spot for the old Wipeout games and the similarly-aged N-Gen. Pacer (a touch light on tracks but a perfect spiritual successor to Wipeout) and Jetborne Racing (basically a tech demo and extremely demanding with a gamepad, but worth checking out)
