I am not sure what the storm in the teacup is all about. Games have paid for DLC, and someone will ALWAYS say that it 'should' have been included in the first place. There was enough preliminary information, from leaked copies and the like, that EVERYONE knew there were only about a 20% amount of Premium cars in the game. They could have canceled their purchase if this is the game-stopper they like to pretend it is.
It isn't.
I am much more heartened by the promise of monthly (or even bi-monthly) patches. These are the ONLY things I care about. The GAME (it IS a game, no matter how much some try to turn it into a religion!) is horribly flawed. Not the car models. Not the track models. THE GAME.
FAR fewer A-Spec events than GT4. One of the easiest things to fix. I can sit down with a pen and paper and probably come up with dozens in an hour. We already have all Lambo events. Where are the all Aston Martin, or all Skyline, or all FordGT, or just all Viper? It would be easy to create events that allow only cars with an equal HP to the event's top Typical Opponent'. Why is there only a tiny number of Miata Spec events? Why are only a fraction of the available tracks used. Vipers on EVERY track, Chevy's on EVERY track... Those are REAL 'Series'.
This ain't rocket science. And, unless the game was SO poorly coded as to disallow the inclusion of extra events in the menu structure (how can anyone with an IQ over 75 NOT think about this possibility?), a simple patch could allow this in next to no time.
More License Test, more Special Events, maybe a tad harder to code (I think many of them use scripted AI instead of the usual one) but still a fraction of the effort to scanning ONE Premium Car. And, bottom line, what do you want? 1000 Premium cars playing a 🤬 up game, or the same 200 Premiums and 800 Standards playing a FAR deeper, rewarding game? I know where I want my improvements to come from...
And online... well, don't even get me STARTED about how this piece of puppy poo could do with a LONG hard look at its' competitors and see where it is wrong. For starters... credits. I got to grind LTW because racing online causes car wear that I GOT to fix?

We can't make a multi-class race because the idiot leaderboard closes down 30 sec after the race has ended? The Lobby doesn't display cars needed until you get IN (unless the creator has enough brains - which most of them apparently don't - to put the requirement into the title) and look around. No easy One Spec, no lap times leaderboards....
These are SIMPLE patches, folks.
And if Kaz gives a 🤬 about the game users, THIS is what he's going to be working hard on for the next 12 months. Then he can start to think about expanding GT5's cars or courses (personally, I'll take a course over a dozen cars any day of the week and twice on Sundays!), and I'll happily pay for the DLC. But I'm not paying a PENNY until I have more events in A-Spec and a better online experience.
Time is ticking, Kaz-san.... Wax on, wax off. Wax on, wax off. Way I see it right now, he just wax off!
