Wild Apex Rally (2016) - Every PC Rally Game
Wild Apex Rally by mindboiler/Imants Berzins, 2016.
This is a free, tiny rally prototype from two developers on itch.io, which you can find here: https://mindboiler.itch.io/wild-apex-rally
Whilst making a single wheel downhill rolling game (really! https://mindboiler.itch.io/rollhill) they wondered what it might be like if it was a full rally style game, so they tweaked up a Unity Standard Assets Car Example to look more like a buggy, and gave you a single stage to try it on.
There's no real substance here, no engine noise (just gravel), no timer (a bit of a shame!) and no end as such (as you fly off a cliff, back onto a lower part of the track!). The entire prototype is shown in this one short video :-)
Fun for a few minutes! It's another Unity game though, where I found if I run at 100hz refresh rate the game is much smoother than 60hz, 120hz or 144hz, as it looks like many Unity games 50hz physics/framerate internally, hence this being 50fps here.
