I don't wish they were back, but I always find myself with the feeling that Le Mans and all related competitions and series have a vast potential that has not been explored. Partially because many of the top manuracturers of the world have their noses so deep in F1 it's impossible for them to consider serious efforts regarding Le Mans and other stuff.
Hopefully this will change in the future.
Would it be possible, to play forever?
The conclusion reached was that a player is inevitably doomed to lose.
