You are correct. Technically a snapshot, but unmodified files are not duplicated from the previous. Imho that is one of the key things to understand about how git works ( and why rebasing and branch manipulation works so well)

To piggyback, the true main difference is svn stores commits as snapshots and git commits are deltas from previous. This is why git is depicted as a tree since it’s inherently a node-based structure.

Might sound odd, but I loved Dark Arena. Basically a Quake-esque FPS but for the GBA.

Only off about 3 billion or so, not that far!
