...Anime commentaries? Or some sort of shonen-esque machinima series?

You shouldn't jump to conclusions without doing basic research. Trigun Maximum was released after Trigun, when the original magazine that published it died, and so it is a continuation under a slightly different name. Similar deal with Rozen Maiden and Rozen Maiden II. That's the meaning I intended which I thought was obvious if you knew or looked up the title of the series.
