Is hotseat play supported?

Why is there no choice in the game between asymynchronous games and games in live mode?

Hello How many hours is the campaign going?

I keep having a weird noise in the background when I play, how do I fix that? Also, is there a way to play vs AI?

3 out of my 4 wins (2 on AI's turn due to flame trap) - game stops when I get to 10 points and I have to exit via menu (all keys continue to work). Continuing after exit restarts match from beginning. Only one game has finished successfully.
