I could come up with a million excuses for PD, if they actually deserved that support, and indeed in the past I have, when it was justified, except I can't any more with a good conscience, due to their lack of prompt delivery and one of the worst lacks of communication I've ever seen from a software company. (No, btw, just in case you're about to reply what I read too often from others, it's not a "Japanese thing". I've never seen PD's imperious "we will tell you what we tell you when we decide to tell you...and we'll do so in vague, misleading terms and excuse it because we're Japanese" attitude from Japanese semiconductor mfgs, not from Japanese automation component mfgs, Not from their automotive sector, and in gaming, at least not from Square Enix (FFXI). Nor have I seen that attitude displayed by the many Japanese engineers and scientists with which I've worked over the years)
They pretty much showed their cards when they released that addon for privileged rich folk in lieu of providing the missing content usable by ALL the licensees of GT6, (not just the jet-set rich 0.1% of players), ie, the content that of course is still missing after 6-1/2 months and has no official timetable for release. I am well aware of how the NWO game is played. They're using this version as a beta for GT7 on the PS4, neither of which pertains to the software they sold me for the console on which it is played, instead for the next version which I do not own and am more and more unlikely to buy as a result of their "clever" tactics.
But we're veering off topic. Fact is, they're changing the physics routinely, and they're not delivering paid content for this game on time. GT7 is a known push and my bet is that they're releasing many changes to the physics so they can use player data as a large part of the development for GT7. That puts this game squarely into the realm of beta, declared or otherwise.
