Would they be forced to recall a part of a legion, or the entire legion, in the case of a major riot? Were allies used, and if so, what were they replaced with after the Marian reforms? Most importantly (as a manner of curiosity for me, since I no longer play the game,) how could a typical player represent the usual methods of garrisoning, before the availability of Vigiles?
Legions weren't supposed to be stationed in Italia, a rule invented by Sulla (and the only measure he took wich wasn't revoked shortly after his death)

Not really sure about the provinces, though. I assume garrisoning wasn't one of the typical legionary functions - the Romans discouraged rebels by making examples, not by visible presence AFAIK.
