It's absolutely my favorite game ever! The profanity filter doesn't always work... but you've probably heard all the words that could be said anyway. If you haven't, you're not old enough to be playing this game. 13+ is what i would suggest, because you CAN take off your clothes. Though Females keep on a bra and panties and males some shorts. It definitely encourages teamwork. You will HAVE to at some point work together with someone else to complete your quests. The dungeon quests specifically, like those for the Top Secret Spy set, require you to join a group and go through Forsaken Abbey and Bloody Gallery. Overall, i love this game and would rate it 10 stars if i could!!
