If it had pre load starting right now I could enjoy if for a few hours on Saturday...

That is awfully generous of them. Good to hear these type of promotions going on.

Will definitely try it out. Good deal on this MS. I haven't gotten around to buying it. Instead want to get FH2.

Didn't like Forza 5 ( don't like sim racers like I did when I was a kid ) Looking forward to Forza Horizon 2 though. Probably won't buy it at launch maybe on Black Friday.

I didn't buy it either. So I am happy about this. I am more excited by Forza Horizon 2... But Drive Club on PS4 come out around same time.. Not sure if I need 2 racing games.

So we can download it only for the weekend? Does it go dead on Monday? If so, I won't bother.

It's like an enhanced demo, you get the entire game for 48hrs then you will have to buy it to continue playing.

I wish they would do it with AC IV, I could probably plough through that in a couple of days.

It is not 48 hours..   It started today at 12:01am.. and goes until 11:59pm on Sunday..   Thursday- Sunday..    96 hours..    you have FULL access to the game.

How does the download work? I just tried to 'buy' it with smarglass and it shows as 59.99 with no trial...
