What are the differences between art packs?
This game outsources most of the art to the players (there are a few official art pieces, which admittedly look good, but too few) via a system of "insert your own art"
Random players then went and stole a bunch of random furry art from across the internet and packaged it into packs. none of the art packs are official. The name on each art pack (such as "LeLurker") is simply the username of the player who made that pack.
Personally I dislike all of them.
1. they are all messy mix of different artists
2. they make it harder to distinguish between procedurally generated random NPCs with 0 content, and important NPCs with content.
If a character has actual art without an artpack installed, then it is an important named character with actual content
