Knights lets you play as a really nasty character if you so choose, and that's certainly part of the fun. It's also an interesting aspect of gameplay, considering a big part of the theme is how Jedi constantly run the risk of falling to the dark side--indeed, you'll probably often be tempted to see what happens if you pick the evil dialogue options rather than the good ones, if only because most RPGs simply don't let you make these types of decisions. Certain key points in the game will play out very differently depending on the decisions you make, creating lots of replay value. LucasArts also promises that downloadable content in the form of new weapons and other items will be made available via Xbox Live later this year.
