Well I was a Project Cars early release buyer (test team member). It was out for over two years prior to being released two months ago. Both PC and PS4 users each have their own different set of problems that are being addressed (twice now, second major patch is in the works). While it is definitely playable and enjoyable it, too, wasn't without big problems...and it had been in Beta/early release for over two years by users worldwide! I have not had any problems with my current Beta/early release racer, DiRT Rally...yet. It is to be released this fall for both PC and console.
With that said, both Witcher 3 and Arkham Knight, both of which I got free with a second GTX 970 purchase last month, have been massive rollout disappointments. As upset as I am about something I got for free, I cannot imagine the anger and resentment for full price/pre-order buyers.
Vote with your wallets, folks. And with all the social media available to us today unlike 10 years ago (developer/publisher Facebook, Twitter, etc.) they need to hear us roar. Vote with your wallets and let them know it. The louder the chant, the more rumble in the stadium seats, the more they'll take notice. A quiet boycott goes unnoticed.
