Players Manual
The first thing to strike you about the game will be the Players Manual

It has hundreds of pages, far more than any other game, with 350+ screenshots. Indeed, it is so comprehensive that it comes in 3 printed volumes. The first describes how to install the program and start playing a game

It includes background information on the board game World in Flames (WIF), some guidance on how to play well

,and the complete sequence of play

When using all the optional rules, the full sequence of play has 60 phases, 85 subphases, 11 sub-subphases, and 7 digressions. Volume 1 of the Players Manual describes who does what in each phase/subphase and how the game transitions between them.
The second volume covers the player interface in detail, with screenshots of all 150+ forms

Each form has accompanying text describing the form’s visual elements and how to make decisions using the form

The text from this section of the Players Manual is available during game play as context sensitive help. During a game you don’t need to leaf through the Players Manual looking for how to use a form, just click on the Help button to bring up the text from the Players Manual that describes the form

Volume 2 also describes all the optional rules

The last section of the second volume contains the appendices: charts and tables describing keyboard and mouse commands, unit information, terrain effects, and combat result tables. Because the Players Manual is also included as a PDF file (re: Adobe Acrobat), you can print individual pages.

That means you can print your own reference pages of the combat results tables, the terrain effect chart, etc. - if you so desire. Of course they are also accessible during game play from a drop down Help menu on the game’s main form.
The third volume of the Players Manual contains the Rules as Coded (RAC) which is based on the board game’s rule booklet but with up-to-date corrections and clarifications, plus annotated deviations of the computer game from the board game

For players of the board game, this should be a familiar document, just improved for MWIF.
The printed material that comes with MWIF is not some slap-dash affair thrown together as an afterthought. In the Players Manual and Rules as Coded volumes you can see the tangible results of years of effort to make a great game accessible to a wide audience of wargamers.
