I just got GTHD today. We bought a whole home theater system, 46" Sony Bravia LCD TV, 5.1 surround sound and 80 gig PS3 came as a package deal (including 3 blue ray movies and 2 PS3 games, Lair and motorstorm). We don't get the HDTV and surround sound delivered till this Thursday but I brought the PS3 home today. I didn't even care about the other games I got. I hooked up the system and immediately downloaded GTHD.
I must say, I feel kind of weird playing GT"HD" on a non-HDTV. I can't wait till thursday and the full system is hooked up. Finally I get to experience Gran Turismo in 1080p and surround sound. I'll get out the GT force Pro and get busy. It has been collecting dust for some time now. It still works though, i recently tried it with BMW M3 challenge. I can sense my pedals are going bad. They've been doing weird things for some time but they still work so I'm happy. If they die then it's G25 time...
My impressions of GTHD with the controller so far is a slight improvement in the car physics but I have to wait till I play with the wheel for a better judgement. Thank god they resolved the force feedback lawsuit thing. Now I'm all set for GT5 prologue. Lets just hope the release doesn't get pushed back any further.
