ill provide you with my award winning RTS strategy... nobody else look!
i play alot of RTS, and i mean lots, any RTS is my cup of tea, and its because long ago i decided to come up with 'The Theory'
i thought long and hard... what principle serves true for ANY RTS?
i thought about resources... but there are so many, and each game plays very differently...
I thought about the tech tree, but in some cases a tier 1 could beat a tier 3...
I thought about Strategy... but this is the most diverse of them all...
in the end what came as the most vital aspect of your playing style for any RTS is something i call the 'K' factor, how much killing can you squeeze from unit X? by killing i really mean how much objective completion.
In DOW: Eldar (shockingly) play as the most K rich army, they can strike and flee, and farm 'K' from your opponent, reserve your own K, deplete your opponents, thats the key.
In Age of empires, its choosing attrition strategies that can survive with the least maintenance, while inflicting the most damage on your opponents, so while a horde can inflict massive damage, it needs replenishing, artillery however can halt and defeat your opponents strategies.
In Civ? the key is choosing a strategy that goes on working long after its potential is fulfilled, as stated above, the culture option is the most K oriented option, but once again K is just the principle, not he best execution.
So, Pick units and options that have the most K, survivable units with the ability to inflict more resource damage than you paid for them.
sorry for no specific strategies, but i swear by my mouse that the way of the K is the path of the victor
