You know you can use the Xbox pads on your PC right? Either the special windows USB version or get a wireless dongle so you can use any xbox pads you have

Apparently the game doesnt really open up until Sequence 6, the rest is just catching up new players and backstory :/

All you do is copy and paste the folder to the new drive, then delete the clientregistry.blob (or rename it if u want a backup) and then run steam.

It'll update itself and work out its in a new directory :)
