True...now...
But when I started years ago with R3E it did not work like that. There were only small packages. I bought (almost) all of them and even when using their ingame currency (vrP) it is by far my most expensive sim (I'm not into the iRacing rental business), about 4x the price I paid for AC.
Another downside is that you can't play offline. When their servers fail (which used to happen quite a lot) you can't drive any of your bought assets.
That made me step into AC btw...

Nothing bad said for the sim on its own, it's pretty good, AI is fine once you 'tune' them, graphics are good, physics OK, sound is VERY good etc...
