My fave version of AOL was 1.5. Since then they keep adding useless crap, but you can't run older versions without endless unstoppable *new features!* downloads.
Back to the original subject...
When I first started simming (and I won't tell you when since some of you were still in diapers) I played medical and counselor a lot, because I felt comfortable there. And I created characters around those roles.
Later I branched out and played helm, tactical, security and even dabbled in science and engineering. I still try and stay away from engineering, mostly cause I end up with ensigns who know far more about why stuff works than I do.
And strangely enough, I rarely play medical anymore. Prolly cause I do enough of that in RL that I don't need it for fun.
The one I did learn is that creating a character to play a specific post is the wrong way to do it. Create a versatile character and then as you grow you can move around. Ziggy has played tac, helm, security, a marine and a science officer on the Arcadia. And the great thing is, he has the flexibility written into his character to do that.
Just my five bucks.
