They do! If you back at a Reward Tier that contains multiple copies of Godhood (for example, the Chieftain Tier), all those copies will have the exclusive in-game content corresponding to that Reward Tier in them (Temple Site Centers, 3 Dedications).
We will set up a 'late backer' solution after the campaign, so you won't miss out. For this we'll be using PayPal, which will make pledges without a credit card totally possible. We hope to see you then!
They are. We believe a big part of creating your religion is expressing it visually, and these allow extra options for doing exactly that. In-game you will be able to choose powerful effects to tie to the cosmetic dedication statues.
A short time after the campaign is finished, we will get in contact with you about which platform (Steam / GOG) you'd like to receive your game keys on. Reus & Renowned Explorers keys will be sent to you by e-mail as soon as we've collected all e-mail addresses and Steam / GOG accounts.
