They still use Essence? WHYYYYY? It's so outdated that became since v3 a horrible optimized and buggy mess engine. Is it so hard to write new engine for modern systems and hardware? This engine took in january 15 years and they write the 7th version of this pile of garbagre.
Version 4 was DoW 3...? Every update is a "new iteration" for a "good" company. Sadly Relic massively hemorrhaged on essence engine version 4 [dow3, the only game this engine lays claim to, and most likely AoE 4, unless they are going to move it over to 5?]
This is like saying the Unreal Engine is bad cause BlueBalls Entertainment for PUBG has the worst running version of it in recent history. That isn't an engine issue, it is a dev issue. The same applies here, especially when v4 of Essence has multiple ways to achieve the same thing and has been bugged since release, soft locking 2/3rds of its functionality behind a hidden export glitch that corrupts the export. Everything "works" in the builder, but depending one what you changed, you will never see it as it doesn't export properly. Was meant to be fixed in September, don't believe it ever was... Either way.
What you say is completely false.
Unity released in 2005, still used to this day [ffs im using it]
Unreal released in 1998, still used to this day
CryEngine 3 released in 2002, still used to this day [but potentinally on its way out due to CRYENGINE/Amazon Lumberyard?]
id Tech [id Tech 1-6/Doom Engine] released in 1995 [for the public], still used to this day, although previous versions are deprecated.
The list goes on like this forever.
