I bought them for the PS2 for around five dollars each from Gamestop at one point. But I've since sold most of my PS2 games and began replacing the ones I really wanted to play again in the future with the Xbox versions so that I can play them on my 360 with wireless controller and all. I need to look and see if those two Lord of the Rings games are compatible with the 360.
EDIT: Wooo! They are!
