That is not want I am talking about.
God Of War, God Of War 2, God Of War 3, Call Of Duty, Call Of Duty 2, Forza, Forza 2, Forze 3, etc etc are complete games. The ones I am talking about are the ones these half sized games that finish off with a To Be Continued just to milk gamers for all there money.
We are not talking about game like original Half Life trilogy, Resident Evil where they finish off with a few loose ends and that may or may not be tied up in the sequal. We talking about games that are released in a episodal format. This is where the devs planned it from day 1 that there will be more than one part to the game.
Examples
* Halo 2 -> Halo 3. Halo 2 had the cliffhanger ending because the Bungie team was running behind in development.
* Half Life 2 Episode 1 -> Half Life 2 Episode 2 -> Half Life 2 Episode 3
