So many conflicting Stories! Does it or doesn't it? I still can't figure it out!!! Please tell me!

It has (offline), but you sort of, make your own grand prix out of all the tracks. You still need to play 4 tracks, and you get points and such, but you pretty much make your own grand prix.

^Thank you! At least there is some from of a GP mode. I was starting to worry again!
Thanks.

I dont know but you can play online 2 player using console.

Yeah although you'll find the framerate crappy at first (30 fps instead of 60 fps when you play online split screen). It's a huge difference to 60 fps.

No online grand prix though (or if there is it's well hidden, never seen it).

You can also do an online GP, also choosing courses. Saw it in a youtube video

I like the customized GP format.

Both online and offline you can have a multiplayer GP.

What happens is you can set the number of races, and whether to choose each track, whether to randomly choose them or whather to just go to the next track.
So if you wanted you could play a GP exaclty the same as the 1Player GP by setting it to choose the next track and 4 races.... However you don't have to do that as it is now much more customisable.

Its my only complaint of the game that you cant work through it in two player, however this isnt a major fault.

^^not to my knowledge, im gonna feel like a right prat if you can.
