AFAIK there's GPU analogs for everything physicsBody2d's can do, but not directly.

Per particle gravity and forces are batteries included. If you want GPU particles that can collide with other particles there's Fluvio, it's free.

From an apples to apples standpoint. What you're seeing in the video is DragonRuby Entities vs Unity GameObjects (with full functionality).

They look like particles yes, but the intent was to show the creation of fully featured constructs (not a demonstration of "fire and forget" particles).
