It was... it actually felt like a real, modern 911 to drive, it just needed slightly less grip to make it perfect.
GT5 physics don't really get the feel of driving a 911 right... they all suffer from stupid amounts of turn-in and lift-off oversteer. Of course a 911 will show these characteristics, but not at the level experienced in GT5.
In addition, GT5 911's miss that planted feel you get when you've got your trail braking spot on (the front being properly nailed to the turn on the brakes), and you get back on the gas... in a real 911 the feeling is of almost endless grip at both ends... in GT5 you tend to get a lot of front end wash.
In time I'll have to try and tune the RGT to feel a bit more like the real thing.
