Well, this actually brings up a big worry-point for me. I'm not new to 3D. I could easily make a bunch of multi-frame animations and multiple poses and whatnot. I'm hesitant to include a lot of features that would require extra plugins to use. In principle, I don't want to rely on someone's work for my art to be useable, I want my customers to "open the box" and have all the artwork ready to use. But, to my knowledge, with a program like RPGMaker, it's kinda standard procedure, I know the first thing I did was look for plugins when I got it, so it's not so big a deal in this case. And it might be that anybody-who's-anybody is already using non-default animations and I just haven't been paying attention, in that case pfft, whatever, I'll do it.
All the same, I feel like something like a running animation or a full walking cycle might be better as some sort of optional extra. There's a lot of potential for non-default motions when it comes to combat graphics too. I would have to think carefully about what I want to make for people there. Another issue is that if I allow myself to think outside the default template I could easily end up wanting to add more and more animations forever and never finish, which is a dangerous mental roadblock.
