Oops, is this an old discussion? Sorry, I didn't know, but I guess that says something about the issue
Here's the thing though: we don't have a live action category. So, shouldn't live films based on game media go in game, and live films based on anime media go in anime? It just seems sensible. Rurouni Kenshin is an anime series. It has a couple games after the anime, but it was created as an anime and is chiefly thought of as an anime. I think the related films should be in the anime category.
