I never preorder games, except for Stardock games that is. In fact I've been playing games for 15+ years and the first game I ever preordered was Twilight of the Arnor after I picked up Galatic Civilizations 2 (gold pack I think, the one with vanilla and the first expansion) on a whim and got hooked. I had never actually heard of Stardock before that but now I've purchased every one of their major releases since then(Sins, Demigod, etc.)
Allowing paying customers to get into betas is really a great idea and I have to wonder why other compnaies don't do the same. Because of that policy I have preordered Demigod as well and just a few days ago I preordered Elemental. I would have preordered it back when it was announced but somehow I missed the fact that it had been announced until a few days ago(even though I've been looking forward to it when it was still known as not-MOM). At any rate I'll be sticking around for the long haul, although I'll probably be lurking mostly at least until the beta comes out. At which point I'm sure I'll start posting a lot.
