You know.... VH/VH is doable, with some factions its harder than with others. Like with the Romani, KH, Carthege, basically all rich factions have an easier time than the broke factions like Aedui, Saka, Pavhla (sp), etc.

-The main reason is because the AI gets $$ due to scripting, and in the early game of a broke faction it can get extremely hard to beat the incoming stacks without taking too many loses. Oh and don't forget about rebels. That is what mest up my Aedui campain in VH/VH, by the time I killed the Arverni, and was starting to bring up my econ the Romans were on my a** and I didn't have enough men to stop them (nor could I train enough due to little $$, and low MICs). The steppe factions have to deal with the unit making machine of the Seleucids.

-However, EB says you should use VH/M because in M battle difficulty you can "enjoy" the stat system EB came up with. A lot of people like it, me too, but I can't deal with how easy it is to beat the AI so after this campain, I am not playing M anymore.

-Another thing its popular in EB is "Role Playing" that is trying to play as historically close as possible. Especially with the romans. This includes limiting ur tactics to no bridge or top-of-the-hill battles, no all elite unit armies, no spamming slinger, no Rushing the AI, waiting a LONG time to expand or expanding VERY slowly. Only attacking with Generals, etc..... So M battle difficulty is good for that.
