Parents should keep their children away. It's a game about the fun of killing animals, and while I'm not going to suggest outlawing hunting or anything like that, I will point out that most serial killers start out killing animals when they're children before graduating to the big show. You can draw your own conclusions.
Hunters should be warned that although this game is significantly cheaper than organizing your own big game hunting excursion, you're probably going to find this game even more tediously unrealistic than I did.
Deaf and Hard of Hearing gamers should be mostly okay. The game is nice enough to offer an onscreen radar telling you where the animals are. The only thing you'll be missing out on is the 'action music' that cues up whenever a hostile animal attacks, but an 'adrenalin' meter gives the same information noiselessly. Without subtitles, the only major thing you'll be missing out on is the dialogue, but it's not vital to playing the game, nor is it particularly well-written.
