Red Storm air war Central Europe 1987. Complex game, builds on Downtown and Elusive Victory. Lots of detail, lots of air to air.
Not for novice wargamers even Grognards will need a grounding in modern air warfare principles before attempting this one. Precise, technical and strangely addictive.
As ever the VASSAL module makes online play less admin heavy than a face to face game. Game crafter has an excellent set of cards available for the planes and SAMS that eases the chart flipping extravaganza that is part and parcel of the game.
