Did no one read
@OJT6627's post about the plan for a B2B (business to business) version of PCARS? The Mad Box being (primarily) a boxed-PC "console" for commercial use to play that special non-consumer version of PCARS is the most likely and straightforward explanation for this. A good insight on
@OJT6627's part, instead of jumping to conclusions, as I did myself.
Regarding the usual chorus of "buggy and unfinished!" and "poor controller support!" -- I spent last night playing PCARS2 online for hours, winning a few races as well as qualifying and finishing on the podium with the DualShock 4, against a 3/4 full room of mostly wheel users, without experiencing even one bug, glitch, or any network hiccups worse than brief stutters when someone would join or leave a running session.
I will admit I've only just begun playing the game online, having only purchased PS+ recently for the intention of playing
The Crew 2...but between PCARS2,
Ride 3, and TC2, the smoothest and most rewarding experience so far has been with PCARS2, and I think it's how I'll be getting my money's worth out of PS+ for the time being.
On the subject of playing with a controller, there is room for improvement, but the analog stick steering is now way different to how it was at launch or in the demo, and smooth and relaxed compared to PCARS1. It is comfortable enough that I have drifted rallycross tracks until the car runs out of gas.
"Flow" is achievable. Most likely not for everyone, but it's no pain in the hands like PCARS1 was for me.
I was there for PCARS2's launch and I know how bad it was, I know some bugs still remain, and I know which cars to avoid driving (and ones that used to be on that list, but are now fixed). If you are unwilling to give SMS another chance, then don't, and it's SMS's own fault that they have this reputation, but it's a fact that most impressions of PCARS2 from those who haven't continued playing it are out of date.
