Grand Theft Auto IV/Dating

In GTA IV, you have the option to date five women in Liberty City. Each potential date has their own taste in clothes and activities, making each person different. Girlfriends also give a variety of bonuses.

Dating Basics
The basic structure of a date is the same regardless of the girl you are dating.
 * 1) Call up the girl and Niko will ask them if they want to go out.
 * 2) * Alternately girls will sometimes call you for a date if you ignore them for a while.
 * 3) Drive to their home and pick them up
 * 4) Choose a destination for your date. Possible dates include Helicopter Tours, Darts, Pool, Bowling, Comedy Clubs, Bars, Restaurants, and Strip Clubs (not recommended).
 * 5) After the date is completed take your date back home.
 * 6) When you arrive at your date's home you will be given the option to "Try your Luck" or "Say Goodnight." Trying your luck, depending on your date, could result in a PG rated scene in which your girl yells out random and oddly conversational things with the camera panning out to show the entire building.
 * 7) The girlfriends is not required from 100% Completion.

The Girls
There are five datable girls in GTA IV. Two of them are met during the main plotline and three others are met online. You can date as many girls as you like at once and there seem to be no punishments for doing so. It can, however, get hectic keeping five women happy all of which are sending you text messages and calling you. (There is one more girl you can date on lovemeet.com, she's a stripper but to date her, one of the missions in the game will give you the option to kill playboyX or Dwayne. Shoot playboyX! It's really the only way.)

Spoiler
Michelle is the first girlfriend you have in the game. You meet her when you're set up on a blind date by your cousin Roman and his girlfriend Mallorie. She seems reasonable and normal although she always seems to be suspicious of you, constantly asking if you're involved with criminals. Michelle ceases to be datable over the course of the game due to a plot twist.

Spoiler
Kiki is one of the two datable girls on Love-Meet.net (an in-game dating site). She goes by the name LawChick online, but once you get her number you refer to her as Kiki. She's something of an idealist and is always out to save the world. Like most of the characters in GTA IV Kiki is a stereotype dramatized to the point of satire.

Ability
Clear Wanted: Once you get to about 80% likeness with Kiki she will call you and let you know that she has some influence with judges. Being an unfairly persecuted immigrant you can call Kiki and have her clear your wanted level. However, this ability does not work on all missions and at higher wanted levels she will tell you that the cops are serious and there's nothing she can do.

Spoiler
Carmen is one of the datable girls on Love-Meet.com (the other being Kiki.) She goes by the screen name SoBoHoe and is a nurse. Carmen is extremely self-centered and acts as if every date with her is a golden gift from the gods. She also often refers to herself in the third person.

Health Boost: Once you get to about 80% likeness with Carmen she will call you and It's unclear precisely how to use this, but after reaching a certain level with Carmen she'll tell you that she can heal you.

Spoiler
Alex is the last girl that can be dated in GTA IV and can be found on Craplist.com (a mock of Craig's List) under the name LiberatedWoman. She is a rather odd girl always talking about her online friends and her blog whenever you're on a date and lamenting how hard her life is with her father paying for everything.
