Reputation
Reputation is something that you have some control over, but only secondhand. Your reputation is based on feedback received from other gamers. By playing fairly and treating your fellow gamers with respect, you earn a better reputation as players send in complimentary feedback. Play like a jerk, and you're more likely to get complaints instead, sinking your reputation.
Gamer Zone
Your Gamer Zone is something you select yourself. Your initial choices fall into four categories: the Recreation zone, where casual gamers thrive; the Family zone, where parents and younger gamers alike can enjoy family-friendly gaming; the Pro zone, a place for hardcore gamers who don't want to deal with lame griefers; and the Underground zone, where anything goes (and where Family zone gamers probably don't want to go, if you catch my drift).
