Go for it!
You will not have to buy another license, but for some servers you will have to "earn" a higher license before you are allowed to race, by racing on beginners servers or getting the required lap time.
This allows the servers to provide closer races by reducing / distributing skills range, works pretty well
Depends entirely on how the server is set up. Most will let anyone race, but others have software in place so you either can't race at all until you've attained a certain 'licence' on their noob servers (like CTRA and Conedodgers for example) or it limits certain cars for the same reason.
It lets the more experienced drivers race against more level opponents, gives the newbies somewhere to practice in a competitive environment and adds more of a progression to what's a very open-ended sim.
He's talking about two seperate things here. If you buy an S2 license, then you get access to all the cars/tracks and S2 servers.
Some servers(really only one or two that I know of) require you to have a special "license" to race on them. For example, the CTRA servers. There is a server 1 and 2. You start out racing on server 1 with slower cars, and when you get enough points you get a license which allows you to race on server 2 with faster cars. This license is not an official LFS thing, and is only used on the CTRA servers.
They are referring to the CTRA X-System, which is an external addon not related to LFS itself.
LFS has two different licenses, S1 (the old one with limited content) and S2. Third one (S3) is still to come when the game development reaches that stage.
EDIT: Whoops, this was let open as I did my grocery shopping
I am aware that my servers attract alot of attention in the demo section of the sim, because they are so popular. Therefore i am taking measures to ensure that the racing on these servers are kept as clean as possible so that you can test the game propperly. I am putting together a small "underground" admin team to monitor theses servers. The admins have nothing to do with fusion, however they are respectable people with a mature attitude towards their role. I will be taking more of these people on to help combat this issue.
Please DO NOT apply to become an admin. You will be selected.
Also LFS Lapper will soon be installed on these servers with swear filters / spam filters and idle detection.
We at fusion want you to experience the very best that LFS has to offer in its servers, and i am taking measures to ensure that this is the case.
Okay I've got S1, and there's only the CTRA race with players in, but eh, it's better than 20 servers full of smashers!
Hopin to buy S2 sometime next week maybe.
