Allan, I'm not an American, and I totally see Gimpster's point of view. I'm not yet in iRacing, but I will be shortly when a new system arrives, and the reason I haven't been frequenting LFS for a couple of years is very well summed up by Gimpster's comments. Sure, iRacing is a financial commitment, and if it doesn't turn out to be worth it, I completely agree that LFS is the almost the only other game in town, really, so I might be back.
But my point is that Gimpster's not alone. I think there's a whole demographic out there who will lean towards trying iRacing for the exact reasons G. outlines.
