Handmade Network is closely related to games, so this is probably closer to Perforce, heavily used in the video games sector.
It also follows the client/server architecture of Perforce, supports large files, etc. I wish it was open source though, but at least it's free for now.
When it comes to the inner workings, Darke Files is closer to Git than to Perforce. But when it comes to large files Darke Files is definitely taking its cues from Perforce. (Also I've got a few more Perforce-inspired features planned for the future.)
