I have it on PC
The good:
- I can use my G27 wheel without modifications
- Sounds are awesome
- Graphics are awesome
- The "career mode" is more challenging than GT6 (you can adjust the skill level and length of the races according to your skill)
- AI can be adjusted to any level you want and at 100% they are aggressive and fast and you can learn from them
- They have a bunch of nice cars
The Bad:
- You have to be a professional driver to understand how to tune the suspension - lots and lots and lots of options
- You have to tune the car for every track, which means that you can have over 1000 different settings for each car (+40 tuning settings and 40 tracks)
- You have global Force Feedback AND track specific Force Feedback settings...
- On-line racing sucks (compared to what you can do in GT6) (And on PC you can't talk to each other, you have to type... )
- Replays are poor (Photo mode, data analysis, sector times) and doesn't come near what you get from GT6
- I paid $59 for the game less than a year ago. If I want to buy all the DLC content released since then, I have to fork up another $55. (But then, when was the last time we saw a new car in GT6, not including the VGT models....?)
The Neutral:
- The physics are quite different and in my opinion more challenging to go fast, BUT, my GT6 times improved quite a bit since I applied the PCars tricks in my GT6 style.
- Adjustments you can make in PCars correlates more to the kind of adjustments you can make in the real world (street cars have limited suspension adjustments, while true race cars have all the adjustments)
- GT6 can do HP improvement tuning, PCars can only tune suspension performance and you may be able to play with gearbox and final drive settings on race cars)
To me the "Driving Experience" with PCars is more satisfying, but the "Gaming Experience" with GT6 is better
I have still more to explore in PCars, and there is still more to say, but everyone will have his own opinion and preference.
