According to the ESRB, this game contains: Alcohol Reference, Crude Humor, Fantasy Violence, Mild Language, Suggestive Themes
Parents will find that the "fantasy violence" in Steambot Chronicles is, indeed, heavy on the "fantasy": a giant robot kicks the motor oil out of other giant robots. There's occassional bad language (during arena battles, a cheerleader sometimes tells the fighting robots to "Kick some ass!"), andc the game's hero sometimes finds drunks lying in alleys. This sort of material is standard for a Teen-rated RPG. However, you should know that one of the minor characters is stereotypically homosexual, and one of the player's tasks is to meet him in his bedroom to retrieve an item. Nothing is shown on screen, but it's clear that our hero has to do more than get a roll of film.
Gamers who've always wanted to control giant robots may be disappointed; the "steambots" are a bit chunky-looking and are hard to control.
Deaf and hard of hearing gamers should have few problems. You'll miss a line of instructive dialogue during the first boss fight ("It looks like you can jump on it!"), but all other speech is subtitled and there are no significant auditory cues.
