Some of the latest race series in particular have made me *very* glad that T10 pulled their heads out of their arses enough to just let people nab a tune and seamlessly buy whatever CP is needed for the required parts, regardless of car level.
For 'Rulebook Racers' I picked the 1984 Nisssan #11 Tomica Skyline Turbo Super Silhouette, and holy *crap* that thing was just undrivably fierce. Trying to race that thing around Brands Hatch was just... Skill-issue, to be sure, but mostly I'm able to adapt to a car eventually, but not in this case. And then I nabbed a tune. Not some super-duper game-breaking thing; just something that smoothed out some of the rough edges for me.
And it made me sit back and ruminate on how badly they messed up with how things initially worked in FM8, and just how important to me downloading tunes was in other Forza games. In any Forza Horizon game, and previous Forza Motorsports game, any time I got a new car, I would go looking for a cool car design, and some fun tune (generally one that keeps a car in its stock class, unless I had some specific gimmick/purpose in mind).
I'm not a desginer, nor a tuner, but being able to enjoy the fruits of the work of designers and tuners was a big part of the game.
In FM8, I basically didn't bother with downloading tunes at all. By virtue of how the campaign is structured, by the time a given car was levelled such that I might be able to use someone else's tune, I was done with that car and moving on anyway.
Anyway, glad it isn't an issue anymore, and thank you to all the tuners out there.
