I feel like if you're rubberband/afk farming then you lose all rights to say that the economy is being too generous. You intentionally made it generous. People will (hopefully) figure out how to do the same thing with GT7 just like they did in old Gran Turismo games, but it doesn't change that the game economy is really unfriendly to people playing "normally".
To be clear, I don't have a problem with Goliath farming. I kind of like that such a thing exists, as well as the fact that it's not a bug but just a natural confluence of accessibility options. You can have everything almost immediately if you want, but you have to make a pretty clear decision to play the game in an unnatural way to do so.
If GT7 included a similar option I think a lot of the complaining about the economy would go away. People that found it frustrating would have a way to opt out, and people that liked it could continue doing their thing and having fun. But presumably because of the microtransactions thing, Polyphony really doesn't want players to have any options other than slogging through their designed grind.
I will always in every game I play that has a currency or any form of economy find my way to get the maximal economical wealth in the game for the least effort put into it, even if that includes loopholes or exploits found within the game. I exclude external cheats and hacks from that (which I strongly disagree with) and I still need to have fun playing the game. So yes, doing the AFK rubberband controller in FH5 is on my terms perfectly fine. I even held off to that initially because I found it wrong, but after seeing how pathetic their economy system really is, I was like “heck why not get it over with”.
I also don’t see how it’s different from B-Spec in previous GT games, there you also play afk and have your driver do the farming. GT B-spec farming or FH5 rubberband-controller farming, they both feels pretty darn similar to me. In both cases my game is on, the game is driving laps for me and I can go semi AFK to do stuff. In GT you sometimes check how your driver is doing and give him a command, in FH5 you sometimes check how many laps are left and touch a button on the controller to prevent the game going in sleep mode.
Note how I said it still needs to be fun. I read on this forum that the “best way to get credits“ in GT7 is doing a Special Stage Route event over and over. Sorry but that is utterly boring to me and I have no plans whatsoever to do that. Yesterday evening I was just backtracking and playing some career races I didn’t do yet or where I didn’t finish first yet, regardless of their payouts. That includes some Sunday Cup races with only 15k credits payed at the end.
I‘m not going to judge GT7 yet into saying it’s economy system is too hard, i saw that the Ford Mark IV Race Car is now 4.6 mill credits, I bought that car for 20 mill in GTS. If cars don’t cost 20 mill anymore then I think the GT7 economy is just fine.
I don’t mind the micro transactions for credits either. I can easily afford to do so but I won’t use them. But I’m glad it’s an option for people that don’t want to invest all the time in GT7 and if it finances future new free cars and maps in GT7 then by all means I’m glad they are here.
TLDR - I have every right to judge if an economy system in a game is healthy or not, and the one in FH5 is way too easy, regardless if you used the rubberband controller farming or not.
