I made a thread about this 3 weeks ago in a different sub-forum on here, but I figure that posting directly in Help with a more concise OP might help. I hope that this gets answered directly by Bungie, as they're probably the only people who actually know. In this link : http://www.amazon.co.uk/ACTIVISION-Destiny-Xbox-360/dp/B00BF95Q90/ref=pd_rhf_gw_p_img_1 You can see in the product description that Destiny requires a 20GB installation on the 360. What I want to know is A : if the game is Fully Installable and B : if when I "install" the game, it'll be like Titanfall and Wolfenstein : The New Order and forced to play constantly from the disc drive, as opposed to, having a fully installed game where it'll spin for a couple of minutes and then stop (a feature introduced in the NXE update in '08 I think). As Bungie probably know, full installations are an important thing to lots of 360 gamers, and given the choice, a lot of them would rather clear the extra HDD space to fully install it rather than risk damaging the optical drive or residual overheating problems. Personally, I can't feel comfortable preordering this game until I know for sure.
