UPDATE: Well, Sony's getting smarter, it looks like. Now you can download a small installer, and it will take care of installing the game for you. All that deleting for nothing. Still, 27 GB is pretty big. Original post follows.
The only video game store in my town closed down a few months ago, and so it's too inconvenient to just hop by a video game store outside of town and buy some disc games, specifically The Last of Us before it launches in a couple of hours. So I bought the digital version and am awaiting for the game to unlock in just over an hour. My 120 GB hard drive, however, was completely full, and since the game requires a ridiculous 54 GB of free space for installation, I had to go through a huge purge. I've deleted a bunch of games installed and several game data that are required to "decrease loading times" in these days. Of course, when all is said and done my PS3 will have 27 GB of free space, since the install process is extremely inefficient. This will hopefully be the last time I have to do this before new consoles arrive.
You guys have probably done this once or more by now. Are you guys attempting to make space for The Last of Us as well? What are your stories of some epic purging to get some new games or data on your preciously small hard drive?
