According to the ESRB, this game contains: Animated Violence
Parents don't have much to worry about besides cranky kids that will want to return the game. Most of the violence is extremely basic with no blood or gore to be seen, and it's less than you get with most cartoons. No scenes of nudity or questionable language, either. It's boring, but nothing to be concerned about.
Gamers in general should stay away from the game. It's ugly, unappealing and not very much fun to play. I'd wager that most gamers will tire of it in under than two hours.
Strategy fans won't find much strategy here with the weak, nearly nonexistent battlefield tactics and lack of epic scope. It's more like a bunch of people brawling in a big room than a medieval battle campaign.
Might And Magic fans, from what I understand, DragonBone Staff is a big departure from the main series. While I have never played a "standard" Might And Magic game, seeing DragonBone Staff isn't anything to make me want to check out the rest of the series. Perhaps there's some measure of enjoyment here for people who are already fans, but I doubt it.
