FWIW, I echo
@Jordan's sentiments. The T-GT felt good in terms of construction, and obviously, being built in cooperation with PD, suits GT Sport very well with the adjustment dials. The new high-frequency feature is interesting, but felt like a work-in-progress. It has potential, so I'm very curious to see how it is with the final release game. It also seems a little disappointing that that feature will be the exclusive domain of GT Sport: it no doubt contributes to the high price tag, so the fact it only works with one game is a bit of a sticking point IMO.
I tried three or four of the pods on the floor and the wheels felt different from one to the other in terms of FFB strength, so it's hard to say how it stacks up. At its best, it felt very good indeed. Other times, it felt too light, though nothing like the strange lightness of the Logitech/PCARS2 setups that week.
For me, the big question is the intended purpose. If someone is buying a T-GT to play literally nothing other than GT, sure, I get the appeal. But if they're playing any of the other myriad racing games coming out this year, or have multiple systems, there are a lot of other very good options out there for similar (or even less) money. As ever, we're sort of spoiled for choice lately — but wheels are so much harder to try before you buy, and they cost a lot more than a game.
