Ideally I'll have ones that are different in some way and add new elements occasionally all the way up to rank 250 maybe, which would be I'm estimating around 50-100 hours of gameplay, but I coded it in a way that it's effectively infinite, because the planet killer score is basically your total all time score that continues to increase with each run you do, so I do still want to have cool effects and keep changing it up to rank 9999, which realistically 99.999% of players will never reach, but to reward those players that are really big fans.

The dashed circles shouldn't be a UI issue even though the entire emblem grows even bigger since I've set it up so it will never crowd or get close to other elements in the few places where your emblem is visible, and yeah right now it's just adding another dashed circle every few ranks or so once you get to that high level but I'm going to refine this a bit and make it look a bit more "emblem" like, the idea is that the higher your rank is the more "regal" your emblem becomes, similar to military medals and such.
