If it keeps going in the direction of the wind (one day to one direction and one day to the other)...NO.
Graphically speaking (I´m talking as a Full member since October 2011) is really cool yes, but also it has over-saturated textures, effects, lighting...the way even clouds look.
Then physics...cars feels like they don´t have mass, FFB is terrible at the moment.
They keep talking about this and that and in respect to simulation is not even close.
There is too much work to do yet, but they are focusing in graphics and now started with features and career mode. Physics are different at every build and it seems that they are not getting it right.
If GT6 is on PS4 and looking at what PD did with the PS3 hardware...I am not that sure if graphically speaking when it comes to realism pCARS is going to take over GT.
Don´t confuse shiny and beautiful with realism.
Let´s see what happens, but as of now pCARS for me and real simulator enthusiasts, is not even close. I know people that asked for refund. I still have hopes...but not that much since while trying to drive is so unnatural that pisses me off.
