MY best strategy is to first build a forge and rush with 4 romans, then get a solar grid, then bank, then armony, upgrade bank and soloar grid, then max the forge and produce gladiators and Sakata Spiders and Skakata M1-19, just build up (make armory $$$ until everything is upgraded then make it energy, keep building up until you have over 1500 $$$ then demolish bank and make a outpost and upgrade it and get hover tanks & sniper, by the time youve done that have ally make a hospital and get a BUNCH of meditechs so if enemy attacks you will heal, then play defence until enemy sends all troops at you then you just send alll yours (your will most likly win) and you win
--------------------------------------------------------
btw if you dont want to lose as manyt troops in big fight then build meat sheild (cheap units like marines and scouts and romans)you will PWN! tried that strategy 10 times and i won 8 times XD comment on my profile if you wish to hear more strategies
