Basically, this method is just to make sure, because it’s easier to identify through file structure and extensions.
Here’s an example of where the game engine description is located.
RPG Maker
2000, 2003, XP, VX, and VX Ace have the same description but different years, MZ and MV doesn’t have this description
YU-RIS
Wolf RPG
Unity
both il2cpp and mono, 64 or 32 had same description
