I've been dabbling slowly since launch, learning the ropes. I'm a merc pre-orderer, didn't take part in any beta as I didn't have a good enough PC but I built a new one on launch for this and pleased it copes exceedingly well on the graphics-front.
I took my free Eagle out for a spin and can see the appeal of the extra manoeuvrability but I went back to the Sidewinder, put some extra cargo room inside and upgraded the (loaned) fixed pulse lasers to my very own gimbled pulse lasers. It's quite effective now.
Did some bulletin board missions, stole a lot of cargo and sold it on the Black Market in a nice outdoor platform station with no nasty authority presence, been seeking USS nodes and popping in to see if there is any expensive cargo waiting to be scooped, or nasty criminals to kill (lot of funeral processions I've found) and today I've been having a go at shooting some wanted NPCs at a Nav Beacon and made a quick 40k doing that so that's been the most lucrative avenue so far.
My short term goal is to save up 500k (to cover insurance costs) and upgrade my Sidewinder to a Cobra MKIII. I'm about half-way there. Might sell the Eagle for extra cash at that stage too or keep it for fun, I'm not sure yet.
After that, who knows where the Galaxy will take me. I might try exploring a bit.
My favourite moment so far... I jumped into a USS and found some authority vessels fighting a wanted criminal. So I joined in (carefully). Once the criminal was dead and I got a reasonable bounty to pick up I noticed on the scanner that he'd dropped some cargo too. Off to the contacts screen and it said he'd dropped half a dozen slaves. Slaves are pretty expensive I thought but the authorities are still around. But I want the slaves too so I can sell them on... What to do. I waited for a bit to see if the authorities would leave. They didn't. They scanned me and said "all done here, be on your way". Grrrr, not until I have my slaves... So I shut down all my non-critical systems including engines and shields (bit risky I know, but that's what the game is about) and let my Sidewider cool right down until the cops couldn't see me on the scanner and would presume I left. It worked! Once I dropped off their radar they both jumped out and all I had left to do was turn all my systems back on and deploy the cargo scoop. Happy days.
Great game.
