I've dropped out of pretty much all sim racing so I'm not biased. LFS is a dead fish and same goes for iRacing too - it's going nowhere in my eyes.
Boring yet expensive content, non-existing social community with faceless and nameless opponents with forced schedules kill it for me. The SR system is a good innovation nevertheless and hopefully future sims integrate such a feature too.
I'd probably give iRacing another go if I'd be given an option to customize my starting package.
For instance, oval tracks are waste of time for me, so why can't I exchange the oval for a different track in my starting package? Or if I'm not into Skippy racing, why can't I exchange it for a Radical when I purchase my yearly subscription?
Would it be too much to ask if there was two schedules running paraller (what's the correct word?) with a 15 or 30 minutes between them?
