pre-order came early

As long as the game is an original retail copy of the game, then you can feel free to play it. :)

so they cant ban or suspend my account for playing it early (it is an original retail copy)

Hi, please be aware that official support would recommend you wait until release day. People have been suspended for playing games before the official release date. Of course the choice is yours.

ThingOnAString is one smart cookie!

While I won't tell you what to do with your game, I will say this:
I recommend you wait until release day. When games are played early it is rare that the game is a legitimate copy. I'm not saying yours isn't a legit copy, I'm saying these are the types of people you will be playing alongside. Also, when achievements start popping before the game has even been released, the Enforcement team might just start looking to see how it is that these people gained their copies early.

So you're taking a risk playing it early. Again, I won't tell you what to do with your game. But if it was me, I'd wait until the official release day and start playing right at midnight. ^_^ 

If your game is Defiance then you won't be able to play until Tuesday as the servers won't be up & it's online only.

The best thing to do in a situation like this is to just wait until the release date of the game. Players have been banned for playing early from getting games before the release date. My advice is waiting a few days will not kill you. Just think of it as built up anticipation for getting to play it.

it is best to wait tell release day and as Daft badger has said if it is defiance you wont be able to play tell Tuesday anyways since the servers are not open
