Thanks. That's good to know that I can start a download, say "Xbox, turn off. Yes", go to sleep, and then wake up in the morning and say, "Xbox, on" and then play the now downloaded game. Good stuff.
Yea, you can only play the demo 2 times and only 20min per game
Yeah, that was really disappointing. I totally understand the time limit, but the attempts limit is absurd. I literally got to play the game for a combined 12 minutes because I died on both attempts just a few minutes in. Boom, that's it, demo over. Luckily you can sign in with someone else's gamertag (I used my wife's) and get 2 more attempts, but that's pretty silly. There is no purpose of having the demo anymore, so I might as well uninstall it. I would've gladly taken a cut on the 20-minute time limit to 10 minutes, or hell, even 5 minutes, with the ability to play more than twice. That said, the game seems pretty cool. Even if it was only for a few minutes, it was incredibly fun getting into a vehicle and mowing down throngs of zombies.
On the flip side, though, I can kind of understand their concern with giving us too much. For instance, the FIFA 14 demo is pretty generous. You can play a single-player simulation and ultimate team match as well as a multi-player simulation and ultimate team match, in addition to skill games and other things. It's a great demo, but I can easily see someone being satisfied enough with it to just use the demo (probably not that many people, though, and those people likely never would've purchased the full game anyway).
