But which is better the 4GB or 250GB?
The 250GB obviously has more storage space for when you start downloading add-on's & what have you, but it's gonna cost you extra if you want the extra storage space.
Our kids have had the 4GB models for a year now, and they haven't managed to get their drives even 50% filled yet.
Do I buy a package with 2 controllers or get a 2nd wireless one after wards.
As per your phone thread, it really depends on what YOUR plans are for it.
If 2 kids are gonna be sharing it, it makes sense to have 2 controllers ready.
There are plenty of bundle deals out there, I'd personally be going for a bundle deal with Kinect and buy the 2nd controller afterwards (assuming you are going to get the Kinect at the same time).
Is this Kinetics setup worh it.
Definately, but you do need a lot of space.
For 1 person playing, you need to be 6ft minimum from the sensor while allowing for an extra 3ft or so behind you for front/back movements and approx 8ft space for your side to side movements.
