As i mentioned before, this isn't 1999, 2002 or 2005, GT5 has full online capabilities and patches are never out of the question. Now, as you were saying, the game is so extremely horribly tremendously impossible to patch because...? I'm hoping for a fully technical answer that will forever silence me.
i never said it was tremendously impossible to patch a game, you are the one who is claiming it is so easy - you are the one who is supposed bring the proof since you made the claim first.
like i've told you before, i work in software development, and i know from experience that 'patching' a piece of software is not nearly as easy as you make it out to be. the entire piece of software has to be designed from the ground up to have holes in it that allow patching. do i know if gt5 has this? no.
but the fact that i KNOW that ARTIFICAL INTELLIGENCE is one of the hardest things to program in general, from my experience and knowledge of programming in general, and that the AI hasn't changed in the GT series in 5 iterations, makes it pretty easy to assume that it isn't going to change through a DLC patch, especially with how long this game took to come out and it still isn't complete.
can it? of course. will it? chances are about as slim as duke nukem forever coming out.
on that note i'm done trying to talk logically and reasonably with you cause it is a waste of time. at least everyone else can see how dense you are (as if they didnt already know)
