Two things i hate about install procedures:
1) Install programmes not checking the available volume for installation on the disk (as the GB amount required on the back of the box is not always actually required) and then having to pull out of the install after 10 minutes of extracting. Annoying. (CM:Dirt, i'm looking at you as i've literally just now had to delete some crap off my disk for an extra couple hundred MBs)
2) Multiple CDs/DVDs having a play disc which is not the last disc inserted. What is up with that? Why make me install the game via a couple of discs and not leave the play files on the last disc, making me change it out one last time when i try and run the game.
Now, make these better!
