lol, just in case people missed it the first hundred times:
it's not a 3mb install, it's the minimum needed to save you progress. this means that will be NO install for the ps3 version of gtra 4, otherwise that number would have been far bigger.
somebody mentioned gt:5p saying 250kb on the box but installing 5.5gb. that's because gt:5p is actually a psn title by nature, it was DESIGNED to run off a hdd and not a disc. so in actual fact, the disc is never actually in use when you run gt:5p, it's just to prove that you have the game. all retail psn titles have/will be like that. warhawk is another example. it says 468kb on the box, but it installs 2gb worth of data. after that 2gb of data, you will need 468kb for save data.
but because gta 4 is not a psn title, this just means that 3mb is needed for save data, nothing more, nothing less. all non-psn games that require installs (like dmc4 and r6v2), indicate how much it needs to install as well as the save data space.
