Can I make my current campaign's unit scale huge?

[Salah-ud-Din]

I think I left the option for the unit scales as Normal when I was starting my Roman campaign, so is there a way I can change it to Huge? People talk about Hastati units containing over a 100 men, but I only have 82.

You can change unit scale under the graphic settings in the main menu options menu.
It will only apply to a new game, however.

Phalanxes become catastrophically powerful though, beware. As the player, you can pretty much create a front encompassing whole map without any flanks but so does AI. Those phalangites have 240 soldiers per unit in huge settings.

You could use the RomeSage tool, that will modify your savegame allowing you to change units scale without having to restart the campaign.
It is an unsupported tool, make a backup of your savegame first.

Hmmmmmm.....so how do you get past the phalanx problem?

Attack the enemy from two different sides (but that would mean leaving one army to the AI to control)...

You need to surround them while keeping their front occupied with some high defense infantry on defensive mode but you always need to outnumber their phalanx units. Thankfully, I haven't yet seen an army that I couldn't outnumber like that with full heavy infantry armies. Still, elite phalanxes can fight for a long time even if their general dies and they're completely surrounded. Thanks to their absurd melee values, they're not vulnerable to close quarters fighting as well but still manageable unless enemy general is alive and outranks yours by more than several stars.

Since the soldier per unit numbers are high, even if AI doesn't present a large front, their ranks are deep so it takes quite long to cut down these elite phalanxes to the point of routing. You can still forget assaulting phalanx-heavy cities if you're playing with time limit on.

But if the AI was any decent, I don't see myself defeating a full phalangite army ever with any kind of unit combination on huge unit size setting.
