I blogged 9/23/04 (click on this post title) about Star Wars Battlefront on the Xbox. I finished the single player over the weekend, and I had a great time.
But as I said, I got the game for the Xbox Live battles, and that has been a thorough disappointment. LucasArts released a patch about a week after the game came out which supposedly fixed some problems, but in the successive times I have played the game, Xbox Live plays just sucks.
Servers can't be found, after you find a server you get dropped, if you actually get in a game, performance is atrocious. I might give it a few more shots, but with Halo 2 fast approaching, this one might find itself on eBay mighty quick.
