@Arminton Well, and rewards like the founder houses, armor skins, etc. The pet companions as well I believe even though it doesn't say exclusive. The mule mount with the wagon might have an exclusive look too but I'm not sure about the plans for those.

@pedrobillymattos you will be able to reserve your name before Release Start, otherwise it would not make sense after it I guess they will implement name reservation a while before Release, probably 1-2 months earlier. Since we can not count with a Release date before 2021, this function will be also not there before 2021.
