Spinorial: Actually, any game would do. Also, it doesn't need to be a retreat, just a story about a strategy you used against your enemy, or your enemy used against you. The more interesting, the better! Two examples I gave in the OP were actually from StarCraft and Galactic Civilizations.
Hey, that's much easier =p
I used to play more strategic games when I was a bit younger so I don't really remember most of the old battle so clear any more. But I remember one from when I played a bit of Civ5 a few months ago:
Well, well, it may come to pass that not every thing happened exactly that way, and the foe and friends happened to be others, and so the details... But the deep emotion of the time, and the tone of the sheer adventure I tried to depict with the highest truthfulness!
"It was the beginning of an empire, the dusts of the desert roared and the wind sang and a peaceful civilization of the sands crept from the shadow to claim a place in the barren world... We did not want to waste our time with the foolish toys of the military and we crafted the works of the heart. Marvelous cities we built and wonders that all but the blindest did not awe and respected and known we were by all the people of the world we had met, as well as the ones who lived in the very edges of the world.
We had friends, and we avoided having foes, some conflict arose but we always tried to solve things in the best way, avoiding the war as much as possible. And having the King of Ethiopia as a neighbor, a friend and finally an ally!
Happy were the years, and the centuries rolled like a calm breeze...
And then it happened, I couldn't believe as my friend, my ALLY amassed an army and was at my doors! Rage, fervent passion throbbed through my red veins but I was powerless. Ages of peace, years and years cultivating culture and knowledge made me incapable to withstand such villainy ! How? How could this man do such thing with me?
WAR! War made me sick, made me sick with lust for justice... My people run from his legions of destruction but they were keen! We lost too many people, to many soldiers and farmers and cities we lost to ruin but we survived...
Wonders that were devised to smile to the world saw the efforts to theirs creation to stop, and vile machinery occupied the hands of men who were made to sing, write and dance. Mouths which were made to talk of happiness and kindness were devoted to speeches of race, death and madness... But we survived!
I arose the warlike spirit of warriors in deep slumber and they answered my call, everything that could be spared was left to be destroyed and we amassed our forces in our capital while the two other main cities were fortified. We bought help from wherever we could and focused in heavy war machines and specialized soldiers while our scholars left their philosophic deviations to muse about weapons and tactics... The enemy was caught in surprise and didn't expected such fierce resistance and soon weakened their attack, sub-estimating our capacity to adapt and probably thinking that soon we would buckle to their "might" and fall...
They never made a bigger mistake!
Soon our forces came with iron and fire, bestial war-chants echoed in the dark wind and we burned their cities to the ground! The best we took for us and soon we drank cold beer in their old capital, sitting in profane easy over their dead bodies and smiling to the God of War, we had our revanche!"
Well, it was not the most classical war strategy battle report but shows a bit of my emotion at that time, sorry to don't have time to give a better description of what happened that day!
Hope you all like it!
Well, it seems it was too late for trying to get any prize =p But hope someone will get entertained by me humble narrative! =)
