Cortex Expanse

Suppose we do the game using Cortex/Serenity rules?

After my first run through with Cupbearer, I'm less impressed with the system. Calling your hit points/health "Fortune" takes away most of the flavor of describing combat and wounds. Also, the average character can be shot 3-5 times with a pistol before escalating to any kind of injury, so that's ridiculous. I also miss the stun rules from Cortex.
The roll doubles for points and the drama die is a little cumbersome, but interesting. There need to be more non-combat stunts.
Several skills are noticeably lacking. There's no Streetwise, Dodge or Space Suit skills. Starting with only three skills ( or "Focus") also seems very weak.
The abstract money rules are also lame. Tipping people and bribes are weakened (Mike "I tip him one Income"). I will do some kind of conversion from Serenity Alliance Credits over to some kind of Expanse money.

This all having been said, it makes me want to adapt Cortex. The Drama die and rolling doubles for Stunt Points are the only things we liked, so, we could use Cortex rules and roll a Drama die alongside the normal Cortex roll. In this case, the Drama die would be there only to add flavor and increase the chance of rolling doubles. Now, since Cortex uses larger dice than the AGE system, the chance of rolling doubles is greatly reduced. I would allow players to spend chips to buy stunts, but only once during an encounter. You can add chips and Stunt Points together, but that still counts as your spending chips once during an encounter.

Character Generation

We will start with the standard character generation in Serenity, but your planetary background will come with some required stat modifiers and Assets and Complications.

Belter
1 step penalty to starting Strength
1 step penalty to starting Vitality
Bonus Asset (minor) Belter Creole
Bonus starting skill Vacc Suit d2

Martian
1 step penalty to starting Strength
Bonus starting skill Vacc Suit d2, Technical Engineering d2 or Knowledge d2

Earther
Complication (minor) Branded: Earther
Bonus starting skill Covert d2, Technical Engineering d2 or Knowledge d2

New Assets and Complications
Belter Creole Asset (m)- You speak the patois of Belters, a mish-mash of many languages on a foundation of English with hand gestures and body language used to communicate while wearing space suits. Non-Belters who have lived in space long enough can take this Asset as well, but tend to understand it better than they speak it and have a noticeable accent. A non-Belter who takes it as a Major Asset can speak it fluently with no accent.

Branded: Earther Complication (m)- In the Belt and Outer Planets, your obvious Earther origin brings a negative reaction from native Belters. One step penalty on all kinds of social skill rolls, the penalty stacks with any penalties if the Belters in question also have Prejudice: Inner Worlds. Tycho Station and the Titan resorts are general exceptions.

Memorable: Bone Scars Complication (M or m)- Belters who did not get good bone growth treatment growing up may have surgical scars or minor deformities from improper bone growth and corrective surgery during childhood and adolescence. As a Major complication, the deformities affected your face and appearance and also gives a one step penalty to any rolls involving personal appearance or attractiveness.

Space Sickness Complication (M or m)- Earth and Mars born may not be able to adjust to zero and micro-gravity. Make an Average Willpower (Discipline) roll for minor or a Formidable roll for Major not to become ill and incapacitated. A Belter can take this Complication as well, but receives an extra Complication of Branded (m) for not being a "true" Belter.
