The only "valid" reason people can give is a selfish one. Being they want more content because they're probably bored with the demo.
Somehow they feel it's the devs that should relieve them from their boredom by giving them extra content. They fail to acknowledge or understand only themselves are capable of relieving them from the boredom by buying a license.
Don't want to pay money for a license? Fine, play the demo until the end of time for all I care. But don't come begging, crying or even asking for new content.
You see people opening new threads complaining about feature X or bug Y not being fixed after a whole year or why there haven't been any new cars or tracks while they haven't even paid for a license, have not made any contribution to the community or are hardly ever around on the forum.
Then after being registered as an LFS user for let's say a year and having never made a post they open up a thread "hi, c4n sum1 m4ke me Silva skinz kthx? I wunnit red with tribalz unnit"
Or some people even have the nerve to start a thread and blatantly just ask if someone can buy them a license.
Often explaining how poor they are, how the family hardly has enough money to feed themselves, but they NEED a license.
I realize I'm exaggerating (just a bit though), but I'm seriously getting sick of these threads. Go get a life and while you're at it get a job as well.
I really don't want to generalize people, as I know there are good demo racers out there, most of them bought a license and some of them were even given a license by community members for being valuable to the community. And even that has been taken advantage of.
How about a little give and take instead of always take take take, i need something give it to me!
Oh yeah, some people state they need to have an openwheeler or other fast car to be able to judge the game completely. To these people I would say: if you can't see this is a great sim worthy of your money after playing the demo, then this is not the game for you, please leave.
