...good question asked in the wrong moment because right now there is nothing good about it, neither offline nor online.
Offline so many things are missing (battleships etc.,...) the campagnes and single missions are boring and made in a sloppy and negligent way, online its not better. You only have warping planes and missing sound.
All in all its no fun !
Maybe you ask that question again in a few months when they will have patches to fix the crap. Normally you expect patches to fix bugs and stuff, here you have the opportunity to watch how patches cause other crap, (example - proppitch 109) so better wait, maybe half a year until the worst will be hopefully ironed out.
At the moment you better go and play "fishing simulator", that is probably more fun!
