I got battlefront on the PC installed tonight and played it for about 4 hours.
Im sufficiently hooked. Very good game IMO. Kinda hard, but there are a lot of different maps and levels and styles. All the vehicles from Baka tanks to speeders and some stuff I have never seen before. Can fly X wing and Tie fighters. Basically everything you see in the movies is flyable almost anyway.
You can be the rebels from Lukes time. The Stormtroopers from Luke's time. Clones from the Clone wars. Droids from the naboo invasion. So far that is all I have played. This should keep me plenty busy until Halo 2.
