fomalhaut - well Britons is a nice campaign, strategically speaking.You can conquer the island and then you have options ;-) That's where I want to get.As for your suggestions I was never fond of eastern nations.Still Baktria sounds tempting :-)
I thought of a Barbarian Nation, and as in vanilla I thought the Gaul will be too strong, Spanish ARE strong and since I saw nobody talks about Britons I opted for them.

TheLastDays - I had two battles in that campaing.The first I used the generals in skirmish mode (their javelin damage sucks too :-P).The purpose was to lure the enemy infantry and encircle them with the chariots hitting from the flanks.Didn't work as my infantry broke VERY fast.
The second time I thought I could strengthen the morale of my army, by having my three generals atacking from the flanks and the center and the infantry following them.It was a HEROIC melee charge.Failed too cause generals are pathetic in melee.
** The opponent had skirmishers too so it needed a lot of concentration not to get harassed by the enemy javelins.
I still have some more ideas, like having the generalas in skirmish, attracting the enemy javelins then having my skirmishers throwing at them.It will take a lot of MICRO but is worth the effort :-P

Athanaric - I had my first game in M/M.Battles in Medium are quite easy.I don't want to sound like an "RTW geek" but that's my impression.I also managed (with a lot of effort) in my VH/H with Kenon Hellenon, to build a mighty empire - I know economy brings glory after some certain point.Still I want to go for the ultimate challenge and I have read other people play in VH/VH too.So it must be viable.

Vollorix - out of curiosity, what was your phalanx depth? Was it the default maybe?
