Why is C++ still used for game engines?

Low-level control, predictable perf, no GC pauses—essentials for 60fps stability.

Should I build my own game engine in C++?

If you need total control and understand architectures, yes. Otherwise, start with Godot.

Not soon—lacks ecosystem, fights game data patterns. C++ holds the throne.

Everyone bet on C# or Rust killing C++. Wrong. C++ still owns game engines for good reason—raw speed and control no alternative matches.
