I wouldn't mind an offline mode for The Crew. That would things even more fun when you've got bad internet connection.
If they ever come up with a mmorpg racing game that fixes everything 'The Crew' stands for, then I might reconsider.
Also, most people I know only play online when they are alone. When we are together it is all about offline gaming. Devs need to come up with more interesting ways of making offline mode more accessible.
I'm sure there are people out there who would love an offline version. Unfortunately, I am not one of them.
