i voted for a military career
i guess this gives me the biggest thrill in the game
like thurwitt i like bust the bases or even better, do some reconaissance missions.
i like the sky full of ships to blast afterwards, you could leave to hyperspace yes, but that's not funny. i allways liked to be surprised by the "secret weapons" some bases have, like the raising gravity or when the enemy ships start to jump around wild and you can't find a real target.
but i don't mind for whom i work, any colour (flag) is as good as the other, even when my most played savegame is a imperial career.
smuggling goods is (was) essential to me, i haven't those good guides you can have by now, when i started to play frontier back then.
still you find me collecting nerve gas sometimes, until i find a good place to sell it. usually i cheat the cops with a gamesave right on beginning of docking sequence, you can try then different "time accelerations" to evade beeing checked, that works mostly if you don't overexceed it.
also i have allways some minig machines in far out systems to collect some ore there, just to have something different to play when i'm bored from busting bases, or hunting some "bad guys" down.
since i'm not shure what im up to next, i like to have a very convertible ship, not to big and not to small, usually a asp or a constrictor
taxi runs i do mostly at the beginning of a career only to get all the permissions you can have, then i'm off.
