Over G: Energy Airforce

This is a good flight sim and something that the Xbox has been waiting for since the first xbox to be released. Not as good as the Ace combat series on the PS2 but good non-of-the-less.

One advantage is that even though this is a Japanese release, if your 360 is set to English then all of the menus and in game dialog are in English. Big plus for me when I can only read a little Japanese.
