Hi there,
I don't think paying a monthly fee would change anything. The dev team and Scawen wanted to do it their own way and wouldn't change development speed, if there was more money. Money isn't the problem, as LFS seems to be more and more just a side job or hobby in free time like a lot of open source software.
They do it their own way. The way they decided. So no money would be used to get more employees or do it as a fulltime job with just the usual holiday per year.
I am completly happy with iRacing. Sim Racing isn't as popular as other genres and therefore a monthly fee is the right way IMO, if you use it the way iRacing does. New, very good quality real tracks and new real licenced cars every few months with money used for licences and development teams.
I see the monthly fee for serious, fair and organised races every few hours like in a league and gladly pay for content I am interessted in.
This way I can wait for the new patch another 3 years without bothering
I will for sure test it out early 2009
Cheers
RIP
