If there's gonna be a multiplayer in GTA V that will be run by private servers, it wouldn't be that cool. Like what happened in GTA IV-MP; People with low system specs are playing and unlike servers by Rockstar if you're system is detected with low spec you will be kicked. But in the servers run by the IV-MP your system is your problem thats why it's fucking annoying you will see players teleporting and not dying due to the lag. It's also not fun because Rockstar servers have peds and car drive by peds in it which it kinda makes it more fun to play. But if the V-MP will be scripted properly it would be cool.
