Many PS3 users have ached for install options on many games, like Call of Duty, and Fallout New Vegas to name a few, but did they want an install option of this size?  I have a feeling that there will be some unhappy players complaining that the install size is way to big, or takes to long.

I for one, welcome this feature, the Gran Turismo series has been notorious for lengthy load times, but will this monster of an install really noticeably cut down on load times, I guess we will have to wait and find out.

It’s an optional install – you may still play Gran Turismo 5 with a 256 MB basic installation if you don’t have much space. Whole hog, you’re going to need upwards of 10 gigabytes – and 50 minutes – free.

Amar212, a GT5 power user well known on about three forums, got his hands on the game (PAL version) and says its installation screen offers the warning that “install of game data can take up to 50 minutes.” He says it took 40 minutes for him and 6.4 gigabytes at first, but since learned that Grand Turismo 5 will continue to unpack itself during playtime with the game. So keep that 10 gigs free if you’re butting up against your drive’s capacity.

It’s an optional installation, but if you don’t use it, you may expect longer loading screens.
