While each tier has adjustable choices to be made, they do have restrictions:
Nomad's Armory Tier: Can not order inlay items. Can order any boxes, towers, trays, and add-ons.
Nomad's Dice Tower Only (Tower Dive) Tier: Can not order boxes or trays. Can order towers, towers with inlay, and add-ons.
Inlay Options Tier: Has to have at least one item with inlay. Can order boxes, boxes with inlay, trays, trays with inlay, towers, towers with inlay, and add-ons.
The tiers have item restrictions on what can be ordered on a tier, as well as when that tier is expected to ship. We organized the tiers to help shipment and manufacturing pacing, while also not inundating our backers with a different tier for any possible combination of the numerous options in wood types and items we offer people.
While having options is fantastic, overwhelming everyone right off the bat with a million questions is not a great experience. With this system, people can pick what they generally want, and take time to consider what exactly they would like, or wait for wood-types and options to open up.
