OK I've since seen Michael's post that there will probably not be a solo mode.
Beyond that, I can't really say any more than I'm disappointed too. That is a real shame for people who backed the game expecting this and wanting to play offline only. Some of my arguments against solo online mode were based on the fact we expected this too.
His flippant answers of "probably not" I can't really defend. FD really lack communications skills, bordering on the levels of corporate aspergers. Actually it's kind of made *ME* angry.
Regardless of this, I still want the game I paid for. If you are not getting the game you paid for, request a refund. Don't do a chargeback though, that's just a D-bag move regardless of the situation.
NO it's not the Solo but the OFFLINE mode. You can still play alone if you like you only need to be connected to the internet.
