Is the game meant to be unexplained?

Just look to the HOMM V community and the support they get from Nival/Ubisoft in this aspect. The HOMM V community has made a extremely beautiful and detailed manual for HOMM V with the help and support from the developer (Nival) and publisher (Ubisoft). As the manual shipped with HOMM V was totally crap (Nival/Ubisoft admitted as much), the community-made manual is very helpful.

Also with the later TW games (and newer games in general), the game mechanics are becoming sufficiently detailed and complex to be comparable with our experience of Real Life(TM) in some areas.
The gamer may then become more confused with such richness if/when it breaks down in places but holds up in others. E.g. do we expect a certain strategy to work/fail because it would in real life?
Therefore it may be nice to have a guide to temper our expectations of a game that seems to promise so much, but also leave the details of implementation to be discovered through playing :)
