It may be better known under its pre-acquisition name Bitsquid, made by a swedish company called Fatshark. I think the engine part of the company was split off and then sold to Autodesk. Still, certainly not one of the most popular game engines (of course popularity isn't necessarily the same as being the best)
Warhammer Vermintide used it, I believe.
It's "one of the best" because VentureBeat also wrote another article heaping praise on it.
Goat Simulator.

Goat Simulator is Unreal Engine 2.

Unreal Engine 3, actually. The generation (with various iterations) from Unreal Tournament 3, Gears of War, and Bioshock Infinite.
Unreal Engine 2 would be from the period of UT 2k4 and Killing Floor.
Unreal Engine 2 is still quite heavily used especially platforms quite heavily, UT2004 was UE 2.5.
AAA console PC titles also still use it I think the most "recent" ones would be Bioshock 1 and 2. https://www.unrealengine.com/showcase/bioshock-2
Since UE 2 was ported to IOS (Don't recall if it has an Android port also) it actually became quite popular both in porting old games and in making new ones since it's a bit more optimized and is considerably easier to use than UE 3/4.
It might be nice, but I haven't actually met or heard about anyone who would be using it.
