Live For Speed is the greatest race simulator out there, and this is coming from someone who owns Project Gotham Racing 2, ToCA Race Driver 3 and many others.
But there is one serious flaw in LFS. NO MUSCLE. There are alright cars, acceptable at best. The RB4, FXO, RA and the Porsche are the only ones that are good. The problem is, all the cars are four banger ricers (excluding open wheelers, the LX' and the two sports cars). All the real cars that is. They all seem to have ricer four bangers, front wheel drive, etc. Where is the muscle? We need V8 engines, rear wheel drive, 1960s power, imense size.
In short, LFS needs (or I want): 1971 Dodge Charger R/T, 1969 Ford Mustang Shelby GT-390, 1969 Pontiac GTO 'The Judge', 1968 Chevrolet Camaro Super Sport and a 1992 Ford Tempo GLS Sport Coupe (j/k).
