You are thinking in a cardgame frame of mind aren't you? i don't know if it will be a good option.

I would choose:
Weapons: Range/to hit modifier/damage die/special rules
Shield: Damage reduction to weapon die
Armor: Points absorbed from damage/Threshold
Inner Structure: Number of points until kaput
Max speed
Agility (how easy to turn, accelerate and deccelerate)
Pilot skill
Gunner skill
Unit name
Unit illustration

This may change a bit because we are talking of at least four different types of units: Capital ships, fighters, tanks and infantry and that is leaving mecha out of it.

[cgutzmer]

When you say mecha do you mean like big robotic suits of armor? I would prefer to leave those out of it and stick to more conventional stuff like AFV's, infantry and the like

at lest until expansions

Agreed. I like mecha. My wife jokes with me and murmurs in my ear sometimes with a childish voice "giant-lobotta" and laughs. It was after she found out my spoils of Battletech...

Still I'm with you. Mecha can be added (or not) in the future.
