Come on, we all have one.
What war gaming period have you always looked at with half an eye and thought to yourself: one day..!
Always the war gaming butterfly, I have several.
The American Revolution. Caveat - it must be with Stadden 30mm figures. I have always been drawn to the American Revolution because of the Stadden range. I weakened about a year back after spotting some of them here and bought all the named characters (Washinton, Howe and all the others) and some of the British Light Dragoons. I could stop there perhaps, but would keep on looking at the British Grenadiers, and if I have those then I would need some Continentals who would be gorgeous in blue and buff.
Next would have to be what I really only loosely would term "The Great War in Africa". Loosely as it covers the Lettow-Vorbeck adventure, but because there are so many lovely add-ons that you can throw in. Armed sailors in the Rufiji Delta. Germans defending Tsingtao. Australian naval types mopping up German colonial possessions in the Pacific. TE Lawrence doing his thing against the Hijaz railway. I could go on. In effect this is all late stage colonial war gaming with a touch of VSF thrown in in the shape of gunboats, armored cars and biplanes. There is a Heart of Darkness element if you consider the British Naval Expedition to the great African Lakes. All are epic stories in their ow right and together are almost too much to take in. Indeed, I am almost paralysed with indecision.
The Great War more generally. I've always been interested in the early war battle of movement - always so much more interesting than the dreary slog of most of the war. Likewise the later battles of the war when allied armor was able to be used after the last great German offensives of 1918.
And then there is always the war in the air... Something where the players have a roster of pilots available with each his own abilities and a natty 1/72 scale aircraft. Each side gets a squadron of fighters and some specials per mission.
Finally there is the clash of coastal forces as so ably done by Warlord with their fine "Cruel Seas" range. Splendid models, a well supported range and fun looking rules. All I have to do is commit.
