I've Recently downloaded a traffic mod found it a HUGE improvement to game play. Felt like a new game, police chase you. And some cars stop and some pull out at the wrong time and a realistic crash happens. It’s awesome. My little brother and I were using multi seat to have a little two player fun, but didn’t work out so great. I would love to see a split screen mode or even a LAN mode mod. Attention to the professionals in modding! Let’s make this a hole new game again. If the creators see this as well, let’s get the community involved and work together on this one. I think it’s possible and I know we have the developers to make it possible.
I suggest you go and see the FAQ for all the reasons that multiplayer is far out, very far. And also at the very bottom of the list for the devs.
