A topic near and dear to my heart.
From what I've read, the Nero was bloody close to giving up Britain as a total loss over that rebellion and most likely would have, if she'd won.
She came very close to crippling the Roman military presence in Britain and would have succeeded if she had won that last battle - there would have been none left to oppose her. No one willing to oppose her, anyway.
My personal thoughts are that if she'd won, then Nero would have pulled out any surviving troops and officials and ceased wasting resources trying to take and hold the place.
I suspect that the tribes would have gone back to life as usual but the alliances formed would have had future ramifications.
I suspect also that the tribes would have learned that there was more to be gained working together than warring amongst themselves.
The tribes already had mechanisms by which they reduced warring between themselves - intermarriage, fostering each other's children (often leading to intermarriage when the children grew up and married someone in their foster tribe), political alliances and trade.
Such mechanisms would continue, but with the knowledge that their previous divisions had enabled the Romans to invade (especially given that the Romans had made use of intertribal rivalry to gain allies amongst the tribes) to reinforce the need to form stronger alliances amongst themselves.
I can imagine that in the aftermath of Boudicca's successful rebellion, demands would be made that Caratacos be returned unharmed to his tribe - and if the Catuvellauni and/or its allies made use of the post-rebellion confusion to grab a few high-ranking Romans, they may well have the leverage to make that work.
Rome may well have sent ambassadors seeking trade deals in the future, but I doubt they would try attacking in force as they would have put the entire area in the "too hard" basket (as was done with Scotland).
It would completely change the course of history as the British tribes would rebuild and strengthen and forge alliances and would be strong when Rome collapsed, so the collapse of the Empire would not affect Britain as it did in our history.
This in turn would affect the outcome of the Anglo-Saxon invasion.
@ Night: The Romans also gave up if the cost was too high.
Damn it all, she should
