don't waste time or resources BUILDING : get a race that is strong by DEFAULT eg. orcs/humans , build barracks, supply structures, and alter. Put all gold into making default unit [ grunt or footman] and heroes. As soon as u have 1 hero and 3-4 units, go and clear out gold mines to get XP, avoid serious battles until u have the troops/XP for it. when you have a full load of units [16] and your 3 heroes, find some way to spy on your enemy, when his troops are away or when they have been o//ned and are weak, attack the base, take out defense structures , alter and barracks, kill all units u find there, if u have to, run, if u don't , WIN THE GAME.
