If you enjoy racing, and especially if you enjoy online racing, I would definitely get PCARS, and this is from someone who as pretty much played GT online 4+ days a week since GT5 Prolog. It's a completely different experience than GT6. For the record though, as many bugs as there are in pCARS (and it's actually not that bad!), if you are coming from GT6, this should be old hat to you. Especially online. I don't think I'm wrong in saying that pCARS online is much more stable than GT6. Yes, there's some lag, weird stuff happens at starts, rolling starts are broken, etc etc....but not nearly as often or severely as in GT6. There certainly aren't connection and stability issues like there is in GT6. As far as tuning, you probably don't have to tune to race offline. If you want to race online you'll need to, otherwise you'll get smoked. If your main reason for not tuning is because of your experience with GT, and tuning having the ability to make many cars feel the same, you don't really have to worry about that in pCARS. I haven't driven everything yet, but everything I have has been different from one another. The GT3 cars, GT4 cars, and Group A cars are great examples. Each car is unique in how it handles, and in how you have to drive it to be fast. The tuning is more about making the car feel more comfortable / predictable for you to drive, so you can push harder. Think about it this way. Every person who buys a wheel should set up all the settings so that the wheel behaves in a way that they feel comfortable with...and those minor setting and adjustments will be different from person to person. You can look at any individual car in the game the same way. Tuning is like configuring the car for your inputs. But like I said, don't worry about "ruining the feel".
