Commissions include new tiles and or vehicles created to backer specifications within a certain time frame. The Captain pledge allows for one or two floor tiles to be designed, or a variant or two of existing wall tiles. The Admiral pledge is more flexible, and may allow the design of more complex objects or multiple tiles.
If we don't get any Admiral level backers, I will add an hour for every 10,000 SEK we have accumulated. These hours will be used to create new items based on community feedback (post campaign). I will use whichever method is more, so, by this reasoning there will be at least 18 hours of commissions so far (last campaign was around 50 hours).
