NFS Undercover graphically looked pretty identical to Most Wanted and played pretty identical to Most Wanted.
NFS Shift, in my opinion was created by a team of devs that like cars, but didn't know all that much about how actual race cars drive.
It is
unpolished,
Buggy (especially with ATI hardware)
Performance statistics make no sense (No your Corvette Works will not reach 201mph, think more 180mph, Lambo Murcielago Works Upgrade refuses to shift into 6th gear, cripples top speed to 140ish),
The performance bars seem somewhat relative,
Upgrading most cars are worthless,
Physics are completely off. It's like the cars are running 600hp, full race upgrades and then using skinny, family sedan, touring tires instead of racing slicks.
Ride height on some cars are off (or maybe how the game treats ride height/downforce is off), causing them to bottom out and drag on the ground on a fairly consistent basis. This obviously destroys the handling even more. Fixing the ride height issue destroys handling again.
Still keeping rubber banding AI. The AI Will rubber band to keep the front couple cars in front of you. You can have a lap time 10 seconds faster than the rest of the pack and somehow 1 car will always be ridiculously harder to pass than the others. Once you pass them though, you will never see those cars again except to lap them since the rubber band AI turns off after you pass them, allowing you to put up insane leads.
The Rubber band AI also applies to the 1 on 1 car battle races, which makes them unnecessarily difficult.
The insane leads once you pass them means you will never score aggression points. You always end up with 3x more precision points than aggression so good luck with that, small issue but annoying if you like the eliminator races v.s. hot laps.
All in all I guess I'm just venting my frustration, but it seems like NFS Prostreet with a great cockpit view and slightly improved physics. The driving experience is still off and I don't know what the reviewers were thinking praising it so highly. Maybe it's better with a wheel, but expect to go off the track a lot, slide a lot and crash a lot with a gamepad. The basic tire model is IMO the most important thing to get down in a game and this game gives you maybe 50-60% as much .cf as you should be getting.
I wish I would have waited for this game to hit a $20 bargain bin and had some patches. As of now, it's incredibly frustrating, but it's not like PC gamers have a choice, GRID 2 doesn't come out for a while.
I have no idea how the metacritic reviews for this are so high, must be reviewers that don't actually know how fast cars handle, because these are the worst physics I've dealt with in a semi-sim game outside of pro-street.
As it is, It's a 50-60% score game at most if you actually like cars beyond pretty paint options and rims.
