What gods do you like to play?
A few things to get you in the right direction
Never, ever stop making villagers till you have at least 60
Learn and use hotkeys- its soo much faster
Learn and use counters (for instance, slingers who have crap attack and everthing else will slaughter hades uber archers cause they are the counter and get a huge bonus vs archers. It goes like this: Archers counter infantry, infantry counter calvary and calvary counter arhcers. Then heros counter myth units, myth units couter humans and buildings)
DL and watch rec games like mentioned
Learn the maps, its pretty consistant on where the enemy, gold and hunting will be.
Learn about upgrades. For instance, hunting dogs makes your vills gather 30% faster, thats huge. Get that on any hunting map asap. Normally (unless water map) get husbandry if its other than a hunting map. Get pick and hand axe while going from archaic to classical.
Line, mythical and armory ups are big too. If your norse vs hades you would want to get the pierce armor upgrade fairly early.
Scout and never stop scouting, keep checking gold mines
Raid the enemy vills
Shift + click (allows you to input multiple commands to units)
Dont fight a losing battle
Take more tcs asap.
