Re: What video game did you last play?
You don't have to be connected to the net for the games to work, you just need to be connected to the net for multi-player games. Every XBox 360 game I've ever played has a single player option; you don't HAVE to play multi-player, and hence don't have to have an internet connection to play. You do need one for certain DLCs, though; like Left 4 Dead 2. There's a bunch of downloadable content you can get, such as extra campaigns/missions, but only one or two of them will load unless you have a 'net connection to the Xbox. Which makes little sense to me, because you download those campaigns directly to your Xbox 360 hard drive, which means after you've DL'ed them you should have full access to them even without a 'net connection. But nope.
