I'm currently playing Automobilista 2, but always keep an eye on Live for Speed, and test-drive the latest mod cars occasionally.
Automobilista 2 is better than Live For Speed in many ways (which is to be expected being 20 years newer), however Live For Speed still has many important advantages and freedoms that no other sims offer in total.
For example:
- The freedom of CTRL+U
- Physics isn't canned for AI
- Open world levels
- Ability to create courses
