I'd love to have some real AI, unfortunately the whole solo game evolves around that crappy "AI", which you'd rather call "scripted cars".
With a real AI, you can't start at the end and win, unless there is quite a gap in the cars, simple as that. With a real AI, you can't get something better than last place if you spin out, unless someone else spins out.
Which means no 3 laps races starting at the back, and no fun for a lot of people. Which means the whole game needs to be revamped. The whole point of other cars in that game is to hinder the player, they are not here to compete. Like many, i find absolutely no fun in that, but that is how it goes, because most buyers actually WANT that. Forza 4 suffers from the same thing, so did gt5 and forza 3. There is a reason to that, and it is actually simple: most buyers dont want to face an AI. They want to be flattered, and what is better for that ? Being barely able to overtake a couple of cars during a race, while losing positions on every mistake, or make them overtake like they are godlike drivers, recover spins in a breeze, while losing at most a couple positions that will be regained after that many corners ?
Now there is a way to satisfy everyone, but that cost money. We could have a gamemode with an actual AI, that would drive their car like they should, pay attention to their surroundings, trade lines while battling. But is this gamemode actually wanted by most console players ? I don't think so.
I hate driving around with dumb blocks of metal that stand in my way. The only reason i play the solo mode is to unlock cars and get credits, i spend most of my time doing time attacks and drifting, where there is nothing of that scripted cars crap. I want to play a RACE, not "traffic simulator 2014".
Just make an adaptative AI like in live for speed, this works and is easy to do. Couple it with qualifications and call that "racing mode", keep the current system as "arcade mode" or "simulator mode" (i learned the hard way how no racing game is a simulator, but to each their own) and everyone will be happy.
One thing is sure : i did not buy an xbox one and forza 5 because the bloody AI was as stupid as in the previous forza; and i sure as hell will not buy GT7 if it still uses that AI and has such crappy sounds. Having tons of content is nice, but currently the game makes my brain and ears cry.
I really want a game that could replace live for speed, grand prix legends and richard burns rally. These are my top 3 best racing games ever, i still play them from time to time. But they really could use better graphics and sounds now.
