I mean, when watching some SDV player on Youtube long ago, he played with it, and i never liked the idea of seeing something extremely rare, then it'd break the capsule, and nothing happens.
Either keep it whole, or give us an alien, is what i'd prefer.
An alien is most people's favorite, i'm sure and if a second capsule joins, it just doesn't do anything, or gives stuff when broken, i just thought about that.
Maybe some new area, some wasteland with a cave, where the alien will be, and it will remember the farmer, and maybe for leaving the capsule at the farmer's place, it'll do something for you, be it befriending or sometimes giving something nice.
