Cruelty Squad. Also the other assertion seems rather hyperbolic. Steam top50/100 is either unreal or proprietary engines...

Maybe a bit of an exaggeration. But I think at least 30%. Unreal is popular too. Unity seems to be more popular for indie/coop/single player/certain art styles. There seems to be many more unity games overall, but a lot of them are very small.
