Honestly, if this doesn't get you excited, I'm not sure that we can be friends. I say that as someone who doesn't even like pirates and has absolutely no intention of running any of this book with any kind of craft that has a sail on it.
Luckily – I don't have to. All the visual effects in my game are on me. And since I already play Starforged with an overwhelming flavor of cassette futurism, that's where I'm going to be.
Except with better mechanics for trade management, ship and fleet combat, some more bits on structured interludes…
You know what? You can probably figure it out.
Though if somebody puts together a full Oracle conversion for Spelljammer and I can figure out how to play an illithid, it will be extremely difficult to resist that urge.
Just saying. I'm hungry for brains. That's all I'm saying.
