Unlocking planes and difficulty settings.

[Yossarian]

I've finished the campaign on realistic and my friend has done it on arcade and we have the same planes unlocked.

Also I have done all the BoB single missions on sim mode and never unlocked anything different to my friend who had done them also on arcade setting.

that's good to hear because i don't plan on doing much Sim stuff for a while, for me that will be the replay value (and MP of course), but I'll drag it out

According to several people here on forum+Anton multiplayer unlocks plans and other stuff.
