Story Telling

In single player how should the story be told?

Flashback style - Start the game at the last level, make sure the player dies on that level and then when (s)he is dead, backtrack 3yrs to how the player got there.
Like Medal of Honour.

Chapters - The game will be broken down, into say 7 chapters/episodes. At the end of each chapter the player will be presented with a section of the story, or a cut-scene, as the game progresses the story will unravel.
Like the original Doom.

Continuous - The game will start from the beginning, giving an introduction to set the scene, they will then do some training and the action will begin. Cut-scenes maybe added whenever appropriate or have logs appear at random times for the player to read or hear. Briefings could be carried out while in space, so that seconds later you are thrown back into action or the action may even interrupt your briefings.
A bit like Doom3 in that the story unravel as you go through the game.
