noob here.
One quick comment;
Internet racing with rfactor is horrible. If you dont have the servers level of mod, you wont find a race. Infact, I found it frustrating to even find a server with people on it, with out using a mod.
At least with LFS, the servers are usually very active. And very easy to find a pick up race. No need to keep up with a mod, or a mod level.
Imho.
