Pros:
1. Good physics in some cars
2. Nordschleife
3. Mod-ability, possibility to make adjustable and movable apps
4. Graphics
Cons:
1. Sounds top the thumbs down list, although it is quite nice in some cars like the mclaren f1 gtr
2. FFB feels wierd and rattling while standing still in some cars more than other
3. Multiplayer UI, looks intimidating to inexerienced people, you need a guide to even understand how to use the search function effectively whereas there should be easy to understand navigation. It should be clear outside and inside a server what the rules are concerning track dynamics, assists allowed, view allowed
4. not possible to hold clutch and release to engage 1:st gear in race starts, not very sim-ish.
5. seems alot of bugs really in existing content and form, especially since 1.1 and DLC (replays not working for many in certain situations, timing not working correctly etc)
