My deal with my wife is 1 game a month, if there is anything out i want, regardless of new or pre-owned. Sometimes if i get a good deal on a pre-owned title ill get 2 games.
And I thought i was alone in this....lol....
none the less, i noticed skate 3 has a one user only code for certain online functions, but without the code you can still play online...it's just some functions (uploading your own skatepark) that require the code.
