I’m aware of iRacing bulk discounts and used them ( but these are only 15% maximum )if you buy 6 or more pieces. It’s nothing like real packs sales in other games were you get >50% discounts. 40+ pieces of content 20% discount is realistically after you spend >$500 on content alone. Comparing iRacing to other games is not a mistake. Since few years there are few decent free competitions systems(SRS, Simracing.gp, Raceroom’s).You can have great races with the above platforms. But yeah The problem is participation is much lower than in iRacing. I think partially it’s because iRacing has been go to sim for ranked multiplayer for so many years so it became de facto standard. Also many people invested a lot of $ in its content and don’t what to switch to other sim. I don’t think is that bad outside of MP. I mean all the stuff you mentioned (physics, sound , graphics, FFB ) is subjective. Few years ago real drivers said iRacing is most realistic sim. Now, many of them say ACC is the most realistic.
