My Xbox 360 is slowly losing game demos.

Hi there,

using an Xbox One doesn't effect games that are installed on a Xbox 360, it could be a hard drive related issue on the Xbox 360 that is causing this, some game demos also might be de-listed, which means that you can't redownload them anymore via the market
place.

If the game (demo) is still available on the store then you should be able to redownload them

A few things you can try is to clear the console cache, this can be done via the following steps

Go to Settings - System - Storage - Highlight a storage device and press Y, this should show a menu where you can choose to clear the cache. Do this 3x and then restart the console.

Also be sure to check the storage section if it shows any corrupt or incomplete data items. It might be best to delete those, they can be caused by unfinished downloads etc.

Let it know if there were any results

Many of the games on 360 is slowly losing support from developers with regards to online play. Not many gamers play on 360 nowadays.

Demos are still there but have disappeared for some users. I wouldnt be surprised if Demos slowly died off as they actually decrease sales of games instead of helping them

I wonder if it's going to be like PS4 (lacking mostly good backwards comparability) that you have to re-purchase those games or like Xbox 360 games you could play off your old disks (I've got crimson skies high road to revenge from my first Xbox as that's
the first confirmed game demoed).

Also if the list will be limited like 360 games available and not available and slowly releasing them or a full instant restore (every game playable on release).

As tohellnbak said "xbox bing demos" there's a few on there and it is getting updated slowly, so worth keeping an eye on.
