You "write" your own narrative, but if you do nothing but fly into npc mobs and kill them, I am certain you can share JarlFanks view to some degree.
Last game was Cortex, vs Lizardmen, Vs Humans - My mission was to let Lizardmen surive, so I went around and encouraged the hostilities between cortex and humans, but they where rather friendly - however, cortex and lizards where also VERY friendly with each other - so i pushed them to form a non-aggression pact and finally a mutal protection pact - then all it took was a light push on the lizard vs human relationships and we had a nice 2v1 war - i took part in the lizards favor, ensuring they took most of the spoils and sold them the tech cheaply (and not so cheaply to cortex) - while also supporting the humans vs Cortex actions.
In all honesty, just play the demo.
There are far more items and your possible layouts, weapons and approaches get very diverse as you gain higher level, right now I play a engine heavy ship with 2x AoE Electro shields and 2x Shock mines +3 Interceptors, so I ram into the biggest enemy blob i can find, drop mines and speed onwards, poping my battery banks to keep the weapons going. Before that I used a double railgun with weapon enhancements (but they keept missing) and before that I employed a fleet of interceptors + Virus Cannons + Mines.
I like it. Lvl 15 or so now.
