I've seen multiple accounts of this line of reasoning both on these forums and on Reddit that the players who grind Tokyo on Tomahawk just simply don't understand how to play the game "correctly". Given that most players somehow were able to play previous installations of GT in the way it was intended, I find it odd that a significant proportion of the playerbase just somehow collectively lost their minds somewhere between the release of GT Sport and GT 7 and decided that they want to play GT 7 in the most repetitive and least enjoyable way possible. Or, you know, perhaps there's an issue with the game design?
Imagine this fictional conversation with your past self and a representative of PD
You: Man, I cant wait to play the next installment of GT finally returning to its roots so I can again experience the different cars and racing disciplines while earning all the wonderful different cars GT has to offer!
PD: Yeah, we're not gonna have a career mode. You'll spend a few weeks doing catch up events with rolling starts which sort of resembles racing and you can earn some cars while you're at it. It'll be shortlived though. We call them the Menu Books. After that there are of course Circuit experiences and Missions akin to previous games.
You: Well that doesn't sound so bad, I can just experience the single player in a different way then while still collecting my favourite cars.
PD: Actually, most of the stuff in our single player doesn't reward you with much of anything in terms of credits or cars so if you're into collecting cars you're out of luck. We do have some lottery tickets though which can award you a customized suspension for your '14 Golf GTI - if you're lucky, that is.
You: Ok... So how do I buy cars then? I thought that was kind of the thing in GT games.
PD: We'll, you can play the game like we intended and earn a coveted collectable every 4 months or so. Or... you can repeatedly drive Spa 24h, Le Mans or a fictional track event if you'd rather earn them in a more reasonable timeframe.
You: That... doesn't sound great, although I do love Spa and I hear that the weather effects and driving in the night will look amazing. I'll just do a few races here and there and then spend the rest of my time doing what I actually enjoy and buy the cars when I feel like it.
PD: Except you can't. We decided that the rarest cars will show up for sale between intervals of a month or two for a window of few days. If you happen to fancy a McLaren F1, it'll be worth 12 to 13 24h Spa events or in terms of time invested, 12-13 hours. So better get those tire strategies ready!
You: That sounds a bit rough. I have a job, wife and two kids, how am I supposed to find the time for that? I'd also rather not wait for two months for it to show up again.
PD: Well, we actually have an event just for that. Basically you drive around the streets of Tokyo in an endless loop in something that looks like a mix of a Red Bull concept car and the Batmobile and is in every imaginable way the antithesis of a real driving experience. To add some flavour, you'll occasionally crash into the much slower AI vehicles and be rewarded with a time penalty and a temporary breakdown to the cars handling. Sounds great right?
