The learning curve is very, very steep. You'll ideally want a friend there to walk you through it, but there's ingame tutorials too.
I haven't played in years, and couldn't get back into it, but I had fun for a few months. I played with two family members, though, and that helped quite a bit. Two of us got a little TOO into the game and ended up quitting, but we were doing pretty okay for money with just PVE and trading.
I think the game is partly F2P now, too, which might be enough to test the waters.
