Greco-Celts?

[Torvus]

Amusing. I have a campaign where I was the Koinon-Hellenon and I migrated to Massalia, in southern Gaul. It was a fun campaign, with a mixture of Greek troops from Massalia, along with Gallic, Spanish, Italian, and German auxiliaries.

Spoiler Alert, click show to read: 

PS: I think you might enjoy the Keltohellenikoi Hoplitai, a sort of thureophoroi with a Celtic twist. They can recruited by a variety of factions throughout Asia Minor, Greece, and Gaul.

I think i might try your first suggestion since I'm currently playing a KH campaign. I know i said i was the Ptolemaioi, but the desert fighting and the Grey Death annoyed me too greatly.

Does EB feature Auxilliary buildings where you can recruit the conquered nations units? Like in XGM, as pontos take ancyra and train galatians?

In my Averni campaign I have a couple units of Massilian hoplites roaming around. I have them charge into an enemy formation with their swords and then they switch to spears and start expanding their circle which completely disrupts the enemy line. Plus with their capes they look like superheroes . I also used Alpine phalanxes as the backbone of my army when I fought the Romans.

The flexibility of armies in EB is one of it's greatest charms.

.
The line of regional MICs is just for that.

Uh, clearly you haven't played EB before, because all those who play EB know that the major feature of recruitment that EB has is the ability to recruit regional troops in addition and sometimes instead of their own factional troops.

EDIT: Damn, too slow.

EDIT2: @Woadandfangs

Arverni ftw! They rock. I roamed around with Massiliotai, and my elite infantries, in Spain, while fighting with a combined Celt-Belgae-Briton (Kluddargos working with Neitos and Mairepos is just too gay) army in Britannia, a hoplite, lonchophoroi, gaesatae and iaosatae army in Greece and a Thraikian/Skythian army with brihentin and a couple of soldurii in the Balkans. It owns. I love regional troops. I really, really, really, really love the flexibility. My only regret is that my Gauls can't recruit any units that start with 'Iberi' higher than Caetrati, even though they should have the availability, being so close to Spain. Hmm.
