It’s better to play on regular maps, not on Warlords (we can handle Warlords just fine:D)
Sorry, I couldn't log into the forum because I was swamped with work.
So, you're interested in tactics specifically for maps other than Warlords, right?
Playing against humans is not that simple. It's one of the more challenging games. My strategy is quite unusual, but it only helps me win about 100% of the time. As the first hero, we take the demon "Actavia"... she's one of the unique heroes, but she has some starting gold (+350 gold)... (we don't buy any more heroes yet, only if absolutely necessary). But it's better not to spend a single extra coin on strategy. We put all our efforts into finding the "estate" skill for Actavia. We won't focus on a quick Capitol in the Castle; instead, we'll focus on quickly building up our creep and developing an army of ifrits. We upgrade our favorite Castle only to the Prefecture and then "work our butts off" (to put it bluntly) to find everything we need to build ifrits. Then we buy the hero we need (in my case, it's either Nimussa or Rashka, but Rashka is better). On the 2nd week, we buy everything available in the Castle for her, and there we have ifrits and Gogs =). This is power! Then we develop the Castle to the Municipality, and while our Actavia is already bringing in about 800 gold extra, and Rashka is gathering resources, we build a warehouse and try to find enough mercury for devils... we build them =). Then the Capitol, and... it's just a matter of technique...
