Chapter length is less important than actual pacing.
Another thought, is how is the story presented. Not everything uses standard "chapters".
(E.G. in my newest fanfic,
Project:Ignition I'm using a Chapter: Day format (with a Prelude)- Outside of the Prelude, which is 100% Narrator doing Prelude/Prologue-y things that are giving world backstory (As this is a cross-over fanfic, I'm explaining the transition from "Universe A" to "Universe B", and the events that led there, stuff that while relevant to know, isn't direct enough to show in the actual story (The Prelude is a whole lot of History in essence)), and then there's Chapter 1: Lynx of a certain Caliber. But there's another division-- the soon to be released next portion, isn't Chapter 2, it's still "Lynx of a certain Caliber", it just so happens to be "Day 2" of the events. Chapter 1: Day 1 is notably long and full of events, running up to the end of the day. (It also starts right in the middle of the action, rapidly introducing the main character and his rival/friend... it then plays out, with the day's action lasting through the night. Chapter 1: Day 2 is even longer, as it starts earlier, plays into another action scene and carries its way... Of course the actual chapter will consist of many "days"- leading up to a notable change in the story that is going to actually start Chapter 2.)
A broken chapter format like that, yes, it's often seen with video games (Coming to mind are the Armored Core 4 and 4Answer games- Armored Core 4 has 6 chapters- each consisting of a varying amount of missions. The chapters act as overreaching arcs.)
...eh. This post is kinda incoherent. My apologies.
