Lego Star Wars Walkthrough
I was really impressed with the Lego Star Wars game - there is a lot of fun and replayability here! Don't try to do everything on your first pass through - you'll need to return to levels with various characters in order to reach every nook and cranny. Also, don't try to rush through and/or cheat on your first pass! The main thing you need to unlock the bonus features is lots of cash. You can get all the cash you want without any cheating - later levels will give you TONS of cash. Just keep working through the missions, not worrying about the mini-kits or extras - and when you get through the first pass of the entire game you'll be in great shape to then buy up all the extra characters and re-visit all the levels.
I do also have a Lego Star Wars 2 Walkthrough online!

Misc Notes I Don't Know Where They Go :)
Note: I forgot to load my notes for episode 2 and 3 until *many* months later. My notes tend to be very short when I write them, because I jot down basic notes while I'm playing the game and fill them out when I type them in later. So I apologize if they're not complete and sort of disjointed. If you get stuck somewhere, let me know and I'll go back and replay that part to make the notes more complete.
