I'm kind of interested, but I don't understand what stats do(except endurance). Is there a dice system? How are success/failures or hit/misses determined?

Stats are simple:
Strength determines your DAM (damage) with melee and unarmed weapons (so, for every point of Strength, it adds two points to your DAM). Each weapon also has a Strength requirement, so if you do not meet that requirement it will raise the minimum number on the die needed to hit by 1 (so if you have 1 Luck and don't meet the Strength requirement you will never hit).
Perception determines your ability to spot things (so, you are more likely to find enemies that are hiding or hidden objects), and also determines your DAM with energy weapons (lasers, plasma, etc.) using the same idea of every point you get plus 2 DAM.
You get Endurance.
Charisma is your ability to persuade NPCs by modifying the minimum number needed to succeed; for every two points, it lowers the number required by 1(so, a character with 1 Charisma will need a 6 to succeed while a character 10 Charisma will always persuade).
Intelligence determines when you level up (for every two points of Intelligence, it requires one less action [picking a lock, killing an enemy, persuading a character, etc.] to level up).
Agility determines your ability to sneak, and the DAM of guns (using the same formula as Strength and Perception). It also determines how many actions you can perform in a turn, with every two points adding an extra action to the turn.
Luck determines how likely you are to hit, by modifying the minimum required number on the die to hit using the same formula used in Charisma (so, 1 point of Luck requires a 6 to hit while a character with 10 will always hit).

We're using a simple system I like to call 'D6', where only a six-sided die will be used. The die will be rolled during persuasion attempts and in combat, and I'm sure the stats explain how it's used during those instances well enough.

That should answer your questions; I'll also add this to combat and stuff.
