Once was a time people would make fun of the crummy little web games that were made using the Unity Engine. That time is long gone.
The multi-platform engine is now used on a ton of big games (the gorgeous Deserts of Kharak and Satellite Reign are recent examples), but not even they look as good as Adam, a concept movie put together by Unity’s demo team.
Being a movie made specifically to showcase the engine, don’t expect Unity games to be looking this good in the immediate future, but the fact this is made using Unity 5.4 (with a new cinematic sequencer tool) and rendered in real-time in 1440p on a GeForce GTX980 shows that it’s not that far off, either.
