I think this is where personal preference, or simply which one you try first, can have a big bearing on how things seem. Not that you've actually said one is better or more realistic than the other, so I'm not suggesting that. Renato said this: For the most part the difference between the Vee in AMS and in rF2 is down to the tire model and that includes thermodynamics, it´s quite different and actually more accurate in rF2 where temperatures build up very quickly when the tire is sliding which is a significant problem for drivers in the real series. source: https://forum.reizastudios.com/threads/the-reiza-rfactor-2-bundle-is-here.5791/page-2#post-39733 To me it seems people are quite eager to find differences between games, and then having found some difference (which may just be perceived, rather than actual) will find some reason that one or the other is better. But trying different games, even with very similar content, the overall feel is often just a bit different. Something about the game design and the way the environment is presented can make drawing direct comparisons very difficult. People still like to do it though, and it's great to see the rF2 / AMS collaboration because it allows a truer comparison, and it's also great that Renato honestly describes how they are different (or perhaps more importantly, how similar they are). I got the Reiza DLC, albeit on sale as I never bought AMS and wasn't sure I'd enjoy the content (for AMS backers I'm sure it's a comfortable experience, driving the same cars in rF2), but from the small amount I've played so far I'm glad I got it.
