Great idea to be honest, actively use the WEC license and make a whole standalone game around it. I too paid for Le Mans in Rf2 like most people here but can't blame the devs if they grab this opportunity and re-release it that way. Would be cool if Rf2 users get like a 10% discount though hint hint
Anyhow I see WEC booming with the new manufacturers coming in all the time, and the game will feature some interesting new tracks like Fuji too. The tracks are kinda limited just sticking to WEC so I hope future deals are possible to include other tracks, that was IMO the main issue with ACC. The lack of tracks to race on. Now it's better than it was before but the selection is still kinda limited.
Also in an early preview I saw a Youtuber mention the physics felt a bit twitchy and unconnected (forget who it was), so I hope we can reach Rf2 standards by the time the game releases.
