They should have just released this as an expansion or patch for GT5.
I don't see the point in it tbh, GT6 should be PS4 only simples.
I was always a GT fan until I bought my xbox and realised what I'd been missing. GT may just about have the edge when it comes to handling but everything else about it like the menu system just feels so dated.
Most of all the sound in the GT games has always been a big disappointment then simple things like that horrible aliasing you get with the smoke effects.
I'll be waiting for a completely new PS4-only game and not something that could have been done as a patch or a £10-£15 expansion.
