True. It's a shame really, Latin is a nice language.
But still, Cicero should be pronounced [kikero] not [sisero].
Why name a lunatic assassin after a famous real-life orator anyway?
Ok, you`re probably just joking but I`m going to explain it anyway... Now people will need to think very carefully about this.
You need to suspend your disbelief. Nirn is NOT Earth.
You`re making the mistake of NOT putting yourself into the world of Nirn. In the world of Nirn, there`s no such thing as Earth or if earth exists far away, no one of Nirn knows about it. There`s no such thing as Latin.
By that reasoning everything in Nirn has developed entirely separately from earth and everything you see is simply a coincidence when it appears similar to Earth. So for instance, the similarity of the Imperials to earth Romans is coincidence or perhaps even a logcal path all Human species on different planets go through. The word Cicero in Nirn world may have similar but not the same meanings as Earth, therfore, Cicero and similar words need not have to sound Latin at all.
Now of course, WE know that Nirn is a made up fantasy taken from Human ideas of our real history, but that`s not the point, you still need to separate Nirn from such exact critcisms of Latin dialogue, since Latin even if the words used in Nirn
appear latin to us of Earth doesn`t actually exist - on Nirn.
Now if we were talking about a game of real-life Roman Historical times and warfare, you would be well in your rights to criticise Cicero for not being pronounced in Latin.
