Yeah, even now. for some all collision boxes are hitboxes while for some others the defensive ones are hurtboxes, there’s the pushbox/physical extent, proximity block which can mean different things, absolute guard, or that thing-that-SFV-gets-wrong-in-rollbacks that’s, depending on the technical presentation or article, called frame advantage (unrelated to attacks’ frame advantage), rift, sync or curveball (ok, that last one is just a qualifier in a presentation where they don’t mention the actual name they use for the thing).
I remember that technical presentation about Eve Online, from local alliance Goonswarm, about how to mess with the game’s dynamic server management using specific formations where they had concepts such as celestial bridges, grid shaping, boxing a POS, and WTF space.
