I still don't understand how people didn't understand the ISO's...I thought it was pretty well explained in the film to be honest.
Just picked up the 2-pack with both Tron and Tron: Legacy, although it was quite hard to find around my parts. The remix soundtrack should hopefully arrive tomorrow or the day after, so I'm gonna be pretty Tronned-out by the end of the week!
On a side note, did anyone else buy the tie-in game? It was actually suprisingly fun, not the shoddy, effort-less game I was expecting. I'd recommend it if you can find it cheap, the multiplayer light-cycle battles make it worth it!
