A little bit unfair, I know. But I think it's wiser to research first before diving into a title. Coming out of a 3 year iRacing addiction, I'm looking for a new experience. Obviously, I am well aware of how it is and very experienced in racing with real people. So my question is, what title of a game or SIM has the most users aside from iRacing? But that number can also be irrelevant if they are not racing online. So what title is the most popular choice when it comes to hosting leagues / series? And I don't care if it's 5 years old or older. If it has the most fan base of online users, I want it! If anyone tells me to go back to iRacing, I will. Just not now. Thanks in advance! Cheers! P.S. First time posting here, and there is no iRacing sub forum? I know they have their own healthy forum, but RaceDepartment... Well, the name of the site has no excuse IMO.
