It's posts like this that let me know video games aren't for me anymore. I come from an era where when you bought a video game, you could play that game. The entire game. There was no online requirement, although with a lot of games having that option meant you could join others, optionally. There was no in game transactions. Expansions were just that, large feature complete expansions.
This is my preferred business model and I like to truly own the things I buy. I want to buy a game. A complete game. People did this for literal decades. Any argument trying to use idiotic attacks like this poster here is moot because, objectively, it's already been done. It's already been done by Gran Turismo itself. If you prefer live service model, and mini transactions, and all that, fine, that's your preference. Don't sit there and attack other people's preferences though. Some of us have been GT fans before a lot of the posters here were born.
As for me, I'm sad, but I'm not gonna rage or fight about it. Like so many of my other games, this one just isn't being sold to me anymore, so I'm not going to play it. I'll trade it in and never buy another PD game. Like I've boycotted EA games, Blizzard games, Ubisoft games, etc etc etc. I don't "need" to play these games. I have that thing called willpower. I know a lot of humans will buy and play these games all while complaining about them. That's not me. GT isn't GT anymore. It's something different and if people like it, that's ok. I don't, so I'm not going to play. I refuse to play any game that introduces problems it can sell the solution to.
I think the OP and many of the other posts like this are just people venting that PD is abandoning them chasing millennials and zoomers, who seem to absolutely love spending extra money on games and having it delivered to them piecemeal. It is what it is. We're the boomers now and we have to accept it. The good news is, there are lots of "niche" games that cater to us people who want feature complete standalone games.
