It sounds like a good idea, so you know it will never happen. Forza has to pursue the largest audience possible, and that happens to be casuals. As much as I would like Turn10 to reboot Forza Motorsport into something more serious, the serious sims don't get the same returns that the more casual racing games get. So if they rethink FM, expect it to be more like Horizon, or a NFS game, and not like FM4.
At least that's what the sentiment seemed to be when I suggested a more serious sim racing spin off.
You seem to have misconstrued what I meant by a reboot, so I'll explain further:
I do not mean a reboot in terms of turning it into a more serious sim, because A: that's stupid, considering how flooded the market is with them, and B: there's merit in having a 'sim' that is much more of an open sandbox and doesn't automatically assume that those that play it are deep into changing tire pressures to eek out mere seconds of a lap time. I guess what I can call it is a rebuild.
What I mean by reboot is going back to the drawing board and seeing what the Forza fans want, or what needs to be changed. I can think of many: a re-adjusted PI system that doesn't actively punish builds that aren't simply just adding gobs of power, new livery editor options which make it easier and more user friendly, especially for first timers, alongside adding the ability to import images (GT Sport has shown that this is possible and can work for most regards) a reworked career mode (preferably to something that resembles Forza 4's with the event list, though I believe the current one in 7 is a decent compromise, but I still would prefer an event list) changing the storefront and livery selling to Forza 4's style (Though I'll let
@PJTierney chime in and see if that actually needs to be changed since he's the resident paint guru) and so much more.
It especially doesn't get into the litany of quality control issues, bugs, and glitches that have plagued the Motorsport series since especially 6. Look, no game is going to be bug or glitch free right out of the jump - games are hard, infinitely harder then most of us realize or believe - but Forza games lately have been horror shows, to the point where my general patience with T10 especially has grown razor thin. Though it's pretty obvious that said quality control is directly related to Microsoft leaning on T10 and PG more and more as the Xbox brand reaches a nadir with regards to lackluster exclusives and increased reliance on tentpole franchises such as Gears of War and Halo, and invariably, Forza. But that reaches into a topic that encompasses all of gaming as a capitalist enterprise, and how it sucks dry any of the talent that step into it, and for the most part, is one I feel deserve it's own topic at another date.
Basically, Forza Motorsport, as it stands, is a car model that is in desperate need of a completely new model. Not any more of this iterative ****, a complete rebuild from the ground up, with the general base still intact.
Fake edit: adding what Northstar posted, because they're stuff that I didn't really think of:
- Custom championships/races with the ability to select individual cars (AC). They kind of went down this path with Blueprint, but sadly that hasn't been carried over to FM7 (yet at least).
- Livery editor with SVG importing (GTS). Granted I haven't played GTS so I don't know how well it works (perhaps @SlipZtrEm can give some insight on how well it works), but from the outside it seems PD has surpassed T10 in the livery editor department.
- Driver rating system (PC2 & GTS). This one speaks for itself and considering how much emphasis they've been putting on the FRC it's surprising they haven't come up with a system of their own.
- Motorsports focused career mode (PC2). Apart from the weird winter races, PC2 has an awesome career mode that mainly focuses on the motorsports side but also greatly utilizes the street cars in the game. I certainly don't hate FM7's career mode and it's a major improvement over FM5 & 6, but it's not the championship based mode they made it out to be.
