Anything in mind? I bought the game from Steam, which until recently I had used very seldom, but from what I've heard has a dedicated modding community. Hopefully I can get my hands on the essentials...
Mods... let's see...
I will not talk about total conversions aside of mentioning XRM (very combat oriented with pirate sectors being deathzones) and DDTC (shipyard missions that give you a M6+ as a reward ONCE per game and a giant selection of drones for just about every purpouse).
Now essentials (you will have to google them yourself because i'd have to have link a LOT here).
Plugin Manager - Good for installing and uninstalling scripts withoug having to reinstall the entire game (you will probably have to do that quite often).
WARNING does not play well with DDTC and XRM... or any large mods for that matter but works like a charm with normal scripts and ALife plugins.
Commercial agent - You want it because it makes supporting a factory complex that much easier. And you WILL want to have running factories at some point.
Economic and Supply Dealer - Makes sure (or tries at least) the factories in his designated work zone are well stocked with resources (good to have running in sectors with weapon/shield factories because those cna become scarce otherwise).
Prospector - An actually working mining mod that causes your ships to *gasp* MINE ore from asteroid chinks AND actually SELL them. Thay can also be linked to a station for "free" ore supply.
Bounce - If you want to have a large fighter fleet. It's a mod that changes hit detection and prevents fighters from crashing into enemy capships. Skip if you don't want to become a carrier warlord.
MARS - Very usefull for everyone. Makes fighter drones and turrets MUCH smarter basically turning ships or M6 and higher class into drone carriers the drones are infact so smart that they can even grab abandones ships and crates for you (you will have to cap'n'dock any ship they drag over manually tho.
ADS - automates your carriers.
Yaki armada - Makes Yaki much smarter. Lets them send incursions into Argon/Paranid sectors (Can use ADS for enhanced carrier AI).
Pirate Guild - Makes the pirates much smarter. (can use ADS for base protection)
Ok there are probably more "essential" mods out there but i just can't remember right now.
But believe me there are TONS of mods out there that you might find interesting.
