The Feature Request Thread...

Not only because of MP, but it has a huge impact. There are the same classes except for some cars in AMS2, and the active player count is less than half of the LMU. Both games have almost identical LMP/GT3 class physics. Yet, AMS2 has much more content than LMU.

If AMS2 has a career mode, this wouldn't be the case but MP has a huge impact now until career mode is implemented.

Edit: There are also other things like more engaging developers, frequent updates that keep interest alive. Cannot deny this.

 

LMU provides a more polished experience than AMS2 overall.

AMS2 is good and fun, but it has cracks everywhere, and it has been like that for many years now. Won't list them because it would potentially derail the thread, but I believe this unfinished everywhere state AMS2 has does play a role on its lesser popularity.
