Hi Aero-R! A few notes about your post:
1 - FC is very controller-friendly, much more than GT5P. However, controller users have a serious setback. When the car understeers, the front wheels have an auto-correct implemented that takes over whatever you are doing. What happens in that situation is that, even if you are steering as much as you can, the front wheels will straighten (sp?) what the game feels is "right" for them to regain grip. This makes precisely timed braking very important and therefore I think controller users are seriously handicapped if the "racing line - braking zones" isn't used, at least until they know the tracks and the braking distances for all cars (they vary a lot from car to car).
2 - Try the game with the G25. It's a completely different experience, FC has the best FFB implementation I know, it really gives you physical feedback of what's happening with the car. There's a deadzone in the center, but set FFB to "High" and it will be minimum. You'll have to get used to it anyway, but a 1000+ kgs car with slicks isn't supposed to have a "light" effortless steering when driven to its limit.
3 - Yes, AI drivers are morons, I think this game's devs based their coding on what they experienced in GT5P online. They're a bunch of punters, brake-checkers, and all, but with your GT5P experience you'll deal with them fine
. A few clues:
a) If you are closely behind before a corner, they'll duck to the inside and brake hard. Just keep the momentum and go around the outside, they won't try to punt you there, as a GT5P cheater would;
b) If you are in front and, before a corner, you see one AI right behind you, give him room, the guys get so blind they'll miss the braking and will just go off in the corner. If you are in their path they'll take you with them.
3 - About the online, I think you'll find several rooms opened mostly at night. Search rooms with all options set to "Any". One problem you can have is that you won't see rooms where people are racing with cars you don't have yet unlocked (and bought). So, invest some time in offline mode, only way to unlock cars and circuits.
Good luck, hope to meet you online soon! 👍
