I used to play GT back in the day and I haven't in awhile. Its not relevant.
Also thats not an answer. If a new GT comes out and is the greatest racing game ever and sells 10 million unins then it is probably a failure because it didn't sell 15. I think there is a big desire for a new GT but there is also a desire for lots and lots of games. I don't disagree that PS4 needs games that sell but you haven't explained why it needs games to sell as well as Halo. What will happen if they don't? Is your enjoyment of the system tied up into whether that happens?
What the systems need are good games that are successful but what is successful for one isn't going to the same for another.
GT isn't relevant? Wut. Sony has a gold mine of a seller under them its sat on.
This is a lineup thread, not all the games will be relevant to all people. I just think its interesting how popular playstation has been, yet they can't deliver on a brand like halo. It outsold all the ps3 exclusives fps games last gen combined.
