Headphones are a good idea to have, too. It is much better when you can concentrate on the sound of your own engine, and also hear your opponents when they are close.
Also, for the benefit of anyone who plans to play:
I’m thinking there should be some kind of structure to the cars you pick for favorites, in order to provide good competition.
For example: Everybody should have the following in their favorites for one-make “spec” races:
Suzuki GSXR4
Motorsports Elise
Polyphony Digital Formula Gran Turismo
Amuse S2000R1
We may decide to add more “spec” races later on, since they tend to be close, fun races.
Then something like the following:
Group C Lemans car (Nissan R89C, R92CP, Mazda 787B, Sauber C9 Mercedes, Jaguar XJR9, Toyota 88CV, etc)
“normal” rally car (Any of the Subarus, Mitsubishis, Toyotas, Peugeot 206, Hyundai Accent, Ford Escort or Focus)
Group B rally car (Lancia Delta S4, Peugeot 205 T16, Ford RS200) optional, we may not actually use these
Any “LM” spec car (350Z LM, RX7 LM, RX8 LM, NSX LM, etc)
JGTC GT500 class (any one of the Supras, NSXs, or Skylines)
JGTC GT300 class
Normal Japanese supercar (no tuner cars) ie RX7, Skyline, Supra, 3000GT, Evo, etc, max 276hp
Old school domestic (Charger, Chevelle, GTO, etc the '62 Buick would have to be forbidden though, and probably the Shelby Cobra)
Newer sports car, domestic or otherwise (Ford GT, Z06, Saleen S7, Ruf RGT, Tommy Kaira ZZII, etc. No concepts or one-offs. Should be a production vehicle)
DTM or other Touring Car (Audi A4 or TT, Opel Astra or Calibra, Mercedes, Mazda 6, Altezza, etc)
If you are lacking any of the above, I can provide a savegame with any car unlocked that you could possibly want. Just make sure you have a memory card without an existing GT4 save, or it’ll be overwritten.
