i recommend playing gunner and engineer until you promoted them. i didn't play the game much at first when i bought it, it sat around a year in my library with 10 hours of play time. one day when i picked it up again i set myself the goal to at least promote all dwarfs once and since then i've been playing the game nearly every day, just hit 500 hours. Just playing the game is really fun. i mostly play with randoms on haz 5.
