Well... since you get 70k gold in the start it opens up some options.
I'm currently playing as vh/vh romans and captured both Italian Epirot cities in less than 10 turns.
First of all I started gathering troops south and didn't plan to attack them yet. But then I noticed that Epirot had split its forces leaving one of their family members with only 2 groups of some relatively tough phalanxes. So I went a charged with the small force I had ready nearby, killed their general and retreated off the map before the reinforcements from nearby square arrived. The reason why I attacked was that their king was there last round but seems that it was some random family member now

. Still a relatively good catch.
And on the next few rounds I used my diplomat to bribe off everything I could and this was when Epirot made their biggest flaw ever leaving their king inside Tarentum and main army(with elephants and all) right outside it. Bribing that cost me some 40k gold but also meant that in the next few rounds I had killed all Epirot forces inside Italy and maintained most of my military might leading to quick capture of Sicily, Sardinia, Korsika and Carthage.
From there on it doesnt really matter wether you play easy or very hard since nearby opponents are no match to you and by the time you find some tougher opponents you yourself are tougher also.
