This is the perfect time to get some credits. Tell the owner that you will give it back to him for the CPM average. If he gives you the money, you should put the blaster down. He can't call you a scammer or thief, since it was on the ground.
Does anyone have any suggestions as to best type of character to play? I checked the guide but it seems vague. Your can be a theif but only if your a scammer...you can be a combat specialist only in certain areas and lets face it with the amount of billionaire army out there you'll most likely just die right away.
I guess pilot is the only real profession to go for?
There's nothing wrong with doing a thief/spy character your just likely to anger other players who have no issue with paying to have you killed. In fact there are a few players who kill people just for fun.
Mate, this game is boring, Being a criminal is less boring, that's a paraphrase of something keir once said. Hold steady and hold true, A criminal's life is for you. Just for the Love of Jesfa and Syn, don't scam for 70m and act superior. Do something big and great.
I'd try to stick to the thief role. Just think broadly of what you maybe able to do.
Fleur was a well known bounty hunter which I am sure had some sneaky tricks and skills. Maybe try and do jobs for bigger groups as a contractor, building illegally, scouting territory, etc.
I will say that I find it weird that you got upset about finding a gun and taking it with you, then saying your character was planned as a thief anyway. :)
When it comes to it, just imagine what your character is like, what he does, goals, and the stick to it. It may evolve as time goes but it will help give you direction. Then don't forget to role play it.
