The story of Case;Irvine is fairly simple and straightforward, drawing on several facets of the known Votoms world like the recent war, barely underground arena battling, and the acid rain seen in Woodo. There's not exactly enough time to tell a truly original or groundbreaking story, but a lot of background explanation can be skipped because the viewer is likely aware of the setting. This allows just enough time for the characters and arcs to work, even if there's a lack of depth or real originality.
Where Case;Irvine shines is in it's surprising animation. The votoms franchise swapped to CGI mechs in 2007's pailsen files with pretty bad results, though later entries were more acceptable. Case;Irvine goes back to regularly animated mechs with pretty decent results, giving us some of the best AT action in the entire franchise, even if the scale and duration remain limited. I don't know why this entry got special treatment, but i'm happy the AT action got at least one good non-CGI representation in the modern era.
Overall Case;Irvine is a short story that'll work for fans of the franchise, but it doesn't offer much else. Released shortly before Votoms Finder it appears as though the creators were trying to find out if a full spinoff was possible, but Case;Irvine will likely go down in history as an expected but decent entry in a very weird franchise.
