A more direct answer would make that more clear.
Unless you make decisions for CA, you cant speak for CA.

What you mentioned would be fun and enjoyable but would take about 10 years, maybe more.
As i mentioned, i am sure that if CA decided to do it, it would have been released in 2 years sharp.

Maybe, but it makes more sense having maybe overpowered cavalry than spaceships in the Roman period.
Again it depends who you ask, but for me medieval cavalry in pre stirr-up antiquity is no less than science fiction, no matter how you call it.

As you said, everyone is entitled to their opinion, which means I don't have to ask you for it.
Of course not - neither you should expect me to listen to you though.

Total war games have been evolutions of their predecessors, not starting a completely different thing, otherwise it wouldn't be the Total War series, it would be something else.
Yes and no. It depends how you define the term TW and what it means to you. For some its been a few years now that it has become *something else*.

As you said everyone is entitled to their opinions, and I was simply commenting on what you said, I don't want to get into an argument other something like this, so we will shoud just forget about it.
There is nothing to forget - just your sarcasm detector is broken.

!it burnsus!
