This was the first pre-constructed Fate adventure I ran for my group.

Aether Sea honestly runs more like "out of the book" Fate Accelerated than "out of the book" Fate Core. It uses aspects rather than skills, but this was actually a plus for the group I ran it for. Character Creation (even with the addition of Fantasy Races) was a simple 20 minute process as we started playing.

The built in setting is an interesting Spelljammer-esque D&D takes to the stars concept. The included adventure can be short enough for a single night or stretch on for a couple days depending on your group. Creative GMs will also find enough suggested behind the scenes to stretch the adventure into an ongoing campaign.

This product is definitely worth putting a few dollars toward.
