Sorry that I haven't updated the list in a long while! Life got busy, and I'd forget about it when I had free time. I'll be getting it updated tonight though for sure (edit: Updated!).
And yes, through my searches and from the suggestions I've noticed that there are plus-sized characters from games compared to anime, and more males compared to females. It's slightly disheartening, but at the same time it makes me glad to see such a significant list.
But for the record, the fact that I like Suikoden has nothing to do with it. It just so happens to have a lot of plus-sized characters.
