So. Code Geass picture dramas, huh?
This one is relatively short, with the first two being 4-5 minutes long each, and tell a short story from Sayoko (the maid's) POV.
The last two are 2 minutes long each and feature Lelouch teaching Suzaku a bit of history of the Britannia empire.
From what I could get from really bad subs was... Idk. Okay? It has the original voice actors (I think? and it has a bunch of them).
It has a chibi/comedic artstyle and yeah as you probably know, in that slideshow fashion.
I appreciate them being short, and I guess the information about how Britannia was born and how it was related to the Roman empire at one point was interesting, but again, I could understand half of what was going on bc of the subs.
TLDR isit worth it? Meh. They're short so you don't really lose much. Last two were worth it i guess, first two are just boring.
