Interesting name but theres a sticky somewhere on the name sales thread that states what a rare name entails, and i don't think it fits. Maybe if u get lucky 5m max? Xfering names is kinda a pain though so i doubt this would be worth the work.
Edit: i was referring to cupcake as i did not see dawn.
Dawn is actually a pretty cool game IMO. That one is getting closer to a rare name and if i were in need of a new name i'd say i would be comfortable paying 25m....(this is not an offer).
