The game is good. It's some of the most fun leveling up I've had. Be warned, though: Some juicy tidbits like Character Classes, Power Color Altering, Costume Pieces, and the Freeform Archetype require money.
1. Storyline: Not much to speak of. Your character is a Superhero/heroine battling crime in the streets of Millenium City. After defeating the alien invasion for the tutorial zone, your character sets out to complete story arcs around the city; ventures out to crises in the Canadian Wilderness, the undersea kingdom Lemuria, and other locations; and battles supervillains and their thugs in Alerts.
2. Violence: Combat takes the lead role here. Your character can obtain Superpowers and upgrade them, typically resulting in a more impressive animation. Players battle gangs, aliens,corrupt organizations and terrorist groups. At level 25, they may customize their own archenemy, who plays a prominent role from there on in.
3. Sexy Stuff: Characters are of quite "heroic proportions" to match the game's comic-book graphics. Skin-tight and revealing outfits may be worn.
4. Drinking/drugs/smoking: Haven't seen any drug or smoking references in the game, but disguised players may enter a seedy bar in the gang-filled part of town.
5. Role Models: Characters will find themselves doing everything from stopping supervillainous rampages to foiling a bank robbery. Civillians being threatened by criminals can be rescued and will occasionally give the player a quest for their trouble. The Champions are decent role models as well, but there isn't too much interaction with any of them (Aside from Defender, the team leader, who gives out daily quests in the main area of town).
6. Online Interactions: The majority of the community puts the "bad" in "bad sportsmanship". While there are decent folk out there, most of it ends up smothered beneath trolls and unhelpful idiots.
7. Consumerism: As I said, most of the good stuff is gated to non-paying customers. Additionally, an in-game cash shop sells helpful features and extra goodies.
8. Conclusion: The game is a lot of fun. With civillians gossiping about and talking to the player at every corner, the world feels alive and it feels like you are it's champion. It's a great game for kids who want to play at superheroics, too. But do yourself and your child a favor, and disable Zone Chat first. It's under Chat Settings, just disable it.
