Hello. I have the Demo version, And I love it!

It is kinda laggy, but I'm cool with it.
So I'm wondering, Will the full version be any Laggier,
Also, How much data is in the Full version? The Demo itself is around 995 MB. That's fine.

So, to sum it up, How much data is in the full game, And will it be any laggier than the Demo.

If all else fails, I'll get it on the Xbox. Thanks, Bye!
