Re: Is there a way to start the PvZGW2 game over from the beginning?
As far as I'm aware there is no way to purge all of the progress from your account and start over.
Realistically with the amount of time and effort which needs to be invested in unlocking the various characters and accumulating the various customization items I simply can't think of a good reason why anyone would want to completely restart; the only portion of the game that can't be revisited as often as you want at any time is the very first scene where you, as a Plant, spawn in Zomburbia and have to fight your way out as the game goes through its basic tutorial.
