I'm quite new to total war games and I was pretty excited when i found out about the host of mods available for romeTW. i started off with RTR platinum but quickly migrated to extended realism
however...i started the campaign as Rome on M/M...and subsequently got destroyed against Pyhhrus.
Phalanxes seem to absolutely crush me and I can't seem to find a good way to beat them.
I didn't have as much trouble in RTR

E;; so im wondering if it's just pyhrus's army that so powerful (from command and upgrade?) or if im just a complete tactics newbie
The strategy I used during the first go at Pyhhrus was to was to engage him frontally and then outflank him with cavalry and then charge the phalanxes from behind. I used skirmishers to deal with the elephants. All in all i managed to take out half of his army while i lost something like 1100~ of my own; perhaps because two units of my cavalry were easily routed by the thessalian cav. I retreated and brought down Quintus to attack next turn.
So i did this again...but this time i had enough soldiers to outflank some of his phalanxes with infantry...and it proved almost disastrous. even sandwiched between two units of infantry the phalanx held it's own no problem until i was forced to clean it up with my cav. Well I did win...but only after sustaining 350~ more casualties.
I'm not sure to what extent extended realism is more difficult...and if it is the new difficulty im dealing with or simply a lack of tactical understanding. thanks to anyone that replies.
