Well, look at the size of the community. Look how many people are willing to take time to post bugs. Look how many people in the commuity, that ask for help (if it was some arcade rubbsih, where you can do any track without brakes, that wouldnt happen), and then look how happy (most) of them are, when they get better...
You want to know what you get: You get a great Simulation, with a large, (mainly) helpful community. Lots of leagues to join, a one_of_a_kind dev team that acctually interact with the community.
And of course you get free upgrades to new patches.
Just incase you were wondering about S2 Online. It is completely different (although there is more civilisation with the new car :shrug than demo.
In my opinion, if you like the demo, it is almost impossible to not like S2.
