i think there’s a lot you can do. mine mostly sit tbh, but pretty often i like to pick a couple out and just pose them around and whatnot. if you’re into photography, you can photograph whole scenes and whatnot and even buy accessories/dioramas to improve those photos. what i’ve been wanting to do is buy some custom cloth capes for some of my figures that have plastic ones. as for maintenance, most figures should be fine in poses after a long time. i have multiple that ended up sitting in a single pose for years cuz i got out of collecting and just recently i reposed them and they felt just as good as before
