What?
Also - I care way less about the name than I do about the price.
I think it was pretty clear that I was mocking your notion that it would be fine if it was called GT Online Championship but it's totally outrageous that it's called Gran Turismo Sport.
Other GTs also had online - this one being more fleshed out does not justify the full price.
I think this is kinda the sticking point. It's your fundamental misunderstanding that leads to your position. Yes, many previous and contemporary racing games have competitive multiplayer offerings, but they all fail on a very fundamental level which makes them practically worthless compared to what you get in Gran Turismo Sport. Anyone who has spent significant time with an online racing game, be it Gran Turismo, Forza, Project Cars, F1, GRID, Dirt, et cetera, will know that anything approaching clean racing is practically impossible to find unless you organise things outside of the game. First corners turn into destruction derbies and greedy players will never not take an overtaking opportunity regardless of the risk to your race and theirs.
If I had to 'review' the online portions of the games that came before I would be giving them 2s and 3s. Some of them have fantastic features but none of them can enforce even a modicum of sportsmanship which makes them incredibly frustrating to play on anything other than a totally casual level. Mario Kart is a fantastic racing game to play online but it's one of the only online racing games where you get the right kind of experience in public matchmaking - because it's a game where anything goes. Wipeout works pretty well too for the same reason. For more realistic games, online racing essentially doesn't work unless you go to the effort of finding regular people to play with privately.
Whether you consider it to be valuable or not, Gran Turismo Sport's multiplayer isn't just a little more fleshed out than other console racers', it does things in a way which turns online racing from something I never want to do into something I always want to do.
