ROGW is great because it's one of those anime where there is a lot of intricate world building afoot. There's a lot of depth in the world with various magic wielders & warriors striving to build up their power bases while we learn more about the protagonists. Gotta love a cute and earnest mage-girl!

These LE sets are probably not too massively produced, so I think they are valid long term deadstocks if you're happy to stream the series.
