I reall do _like_ scarred lands. It's fresh, exciting, and creative. Has some great crunchy bits that I use.
That said, I can say with almost total certainty that I will never run it. I might one day get to play in it, but I will most likely never run it.
This doesn't speak ill of Scarred Lands, it's just that there are so MANY things to run.
I run my own world most of the time.
I run Greyhawk when I don't.
I run Sov. Stone when I don't run that.
I run Dragonlance when I don't run that.
When I'm in the mood for different, I run Darksun, Spelljammer, Dragonstar, Oriental Adventures, or Birthright.
When I'm not in the mood for DnD, I run Shadowrun. Or Rifts. Or Palladium Fantasy. Or Fung Shuei. Or BESM. Or Exalted. or World of Darkness. or Earthdawn. Or Ars Magica.
It's not that Scarred Lands isn't good, it's just that there is so MUCH good stuff.
