Two questions regarding SH4 1.5 from a new guy

[Qitbuqa]

First of all, since it's my 1st post, hello to everyone on this board.

Now two questions that are of huge interest to me:
1) is there any chance of launching this game offline when I want to play it on laptop somewhere where I have no internet connection?
2) is there any mod that improves AI, but leaves all other aspects vanilla and isn't uber grand scale like for example TMO.

Currently I'm running TMO + RSRDC and while TMO is truly amazing, I'd like to try vanilla game with improved AI only. I take it RSRDC alters the traffic of merchant shipping so I'm planning to keep it.
