Over the course of 2 years, I'll go with 3.5 - 4 million. First month sales? 1.5 - 2 million, probably mid-way between the two. I'm cautiously optimistic.
3 million.
I think as word spreads of how much it has improved it will do better than PC1.
Also, our hobby hardware is expanding and more people are playing sims as they continuously improve.
I would think this one would sell more. Better overall game with a little more notoriety since the name has started to build a good reputation with the 1st game. Gonna guess 3+
I think it will be lucky if it manages to beat the first game. I don't mean that in a disrespectful way or anything, it's just that PC2 is launching shortly before the two big franchises as well as the usual batch of yearly series titles, so people will have to be more selective with their purchases.
We know that it's a difficult times for pCars 2. I hope it will be profitable.
And I don't know when come out the pCARS 3, but I think that the launch of PC3 would be amazing on the premier of PS5. The sales would be amazing. (Of course with full PSVR support)
