I got LL because it is closer to 1st/2nd ed fantasy than most competitors. Having started playing with 3rd, I was curious what I had missed. Basically I had missed simplicity and fun in the pursuit of killer feat/class combos. LL brings you back to basic. If you are a 3e person like me, the AC seems wierd, although I have played enough Call of Chthulu that percentile based skills were plenty comfortable. The way the saves are laid out eliminates annoying math, although you have to hunt for your attack bonus...just like the 1st ed books I have seen. It also has the inevitable "unplayable" characters that so many older players complained to me about. Namely, a 1st level Rogue is freakin useless! No HP, and the skill that are it's forte fail more than they succeed. But then I have almost never played any D20 based game starting at 1st level, because most 1st levels of any D20 game are somewhat sucky. LL like 3rd ed is best played from 5th to 15th levels, and then it is a lot of simple easy to learn fun. Character creation is 10 to 20 minutes so you can actually play at your first session.
Step back into the old school days and enjoy.
