Besides my rather comprehensive wish list baked into the quickstart feedback, I’d like to add these:
Difficulty levels:
Very easy +2 dice
Easy +1 dice
Medium
Hard -1 dice (min 1)
Very Hard -2 dice (min 1)
Expert Needs 2 successes
Perhaps the minimum one dice should go really. If you are -2 dice and you have two dice to start, maybe it is not possible. Anyway, that’s a different way to go that may be boring and doesn’t allow for pushed rolls.
The latter difficulty of two successes is important to distinguish experts from the dnd experience of everyone can succeed at everything
I would love to see the esoteric side developed more in a new campaign or rules expansion, that perhaps a ship is found that has old coriolites in it. With more powers.
Also it would be nice if the old coriolite beliefs have spread to some people in secret.
Bring in a bit more horror in campaign followups. You already have a system in place for it and why not have creatures with mental and blight thresholds in their attacks, effects or mere presence.
I’d love for Ship City to not feel stuck with the factions described in the quickstart. Surely there must be secret cabals within and outside each faction, vying for power or special interests.
