This is more pick up and play than Project Gotham Racing, but it's also the most realistic sim ever made.
The engine for Shift was built up from the ground to enable the complex physic-effects. SMS wants to create authentic racer out of NFS Shift, but different than Forza: Forza isn't the direction we're going in.
Until this point, sim equaled hard, and arcade equaled easy on handling. The team felt that this was more a case of the more realistic games not handling properly, as opposed to sims being hard.
I drove Forza and Gran Turismo, and real cars don't handle like that. Real cars don't skid at 30mph and keep skidding at speed. Tyres, when properly interacting with asphalt grip/slide/slide/slip/regrip and so forth, and with driver input, are very controllable, this goes especially for race cars with slicks.
Not only have sim games not compensating for the lack of g forces etc. but they've been making the cars spin out too easily. If any pit crew gave a real race driver a car that handle like that, he/she would take it right back and tell them to fix it.
I'll say it here ... when the team were at Blimey!, they did probably more than 99 percent of the development on GTR2. GTR2 was too hard. It was too hard because the physics engine was lacking in some areas, wasn't measuring enough parameters quickly enough and in the correct way. Real cars are easy to drive, slow and fast ... take any car on a track with some cheap slicks, and you can abuse it to hell and back, slide all over the place, but under steering and throttle control. You need a skid pan to induce the leery spins I see in some so-called realistic racing games. You'll see what I mean you play SHIFT. It's a generation ahead in this area.
Additionally Ian Bell explains that Shift will have three difficulty modes: a default mode for the masses, who enjoy PGR/GT5 etc and a novice mode for beginners. There is also a pro mode for the hardcore gamers.
He also mentions a little bit about the cars and tracks of Need for Speed Shift:
We have a lot of very interesting cars, very little filler or fluff. So you've read 80 cars or so. That's just the bases. I can't tell you anything beyond the cars that have been shown. Audi RS4, Porsche GT2, Zonda, and so forth. We have 18 or so real world 'locations' with many famous circuits among them. And of course variations for some of those on top.
