my tic tac toe game, please try it

Ok, here is my new tic tac toe game. I re-wrote it because the old one had 100 more lines than needed, all global variables, and less features.It has 3 difficulty levels. Here is the new one, please try it out and tell me what you think. It's under 300 lines of code.

PS. there was another guy that had a tic tac toe that kept score, thats where i got the score idea from.

X | X | 3
--+---+---
4 | 5 | O
--+---+---
7 | 8 | 9
It's a tie!Would you like to play again(y/n)?

eazy mode person vs computer...

You should
do some more error checking, like when you ask for difficulty and the user enters -1.
