I haven't touched LFS since I bought rFactor. Whenever I go back to it after netkar or rFactor it feels numb and lifeless. Plus, pretty much all my old GPL mates now play rFactor or iRacing and that suggests I'm not alone. Anyway, it's personal preference so there isn't much point going on about this really
1. Safety rating
2. Subscription model
3. Social networking thingy
4. Centrally controlled race network
5. Auto-matching system
6. Laser scanned tracks
7. No usernames - nowhere to hide
Can you give me any sim in the last 20 years that has had more new ideas in it than iRacing, implemented so coherently?
It isn't cheap compared to other sims of course, but it's no more expensive than any other hobby. I used to race R/C cars which cost far more than iRacing.
When you consider how much LFS has given you for its price tag, it seems foolish of developers to continue a pay-once system. What's in it for them? It's just business at the end of the day, and like any product, if it's priced too high it will fail. If it doesn't fail, then they've got it right.
