Quick glance reveals it is 2-D (no suprise there)
Roll a d20, add your bonus, and try ty meet or beat opponent's defense.
Roll Initiative, loser moves, winner moves, then launch fighters, then initiative winner attacks 1st, then initiative loser attacks. Damage dealt at the end of the round simultaneously.
Stat cards have "Full-strength" and "Reduced" stats.
Movement looks mildly detailed, but not complex.
Ships look to be in "relative scale." meaning the fighters are all similarly scaled, as are the small capitals, and capitals, and the huge ones.
