It's quite simple really. If it's been released officially by Rockstar, it's not a spoiler. If it comes from a leak it's a spoiler.
So we can't discuss things in previews. FYI, a lot of the map was "visible" in all the pictures of the CE and stuff released from R* with the blueprint and somebody put it together (damn close) from the GTAF.
I get it, you don't want to be spoiled. But it really isn't "that simple" since previews aren't "officially released by R*". I agree that the map should be linked, but honestly the GTAF one is so damned close it's practically been known for a few weeks now.
My question, if something as simple as a screen of the map you'll see before you even put the game in your system is considered a spoiler, why even be in the OT? It makes no sense ... unless you really just want to be "that guy".
In MP3 you have a sort of tabbed window in multiplayer that lists your friends and a separate one for crews. You can check your crew page and select someone whose game you can hop in if it's open.
From the little I read GTA:O will have a matchmaking system that tries to get you in a game with your friendslist or your crewmates before sending you pub. I'm sure there will be some sort of system to find and enter your crew games but we'll have to wait a bit more to find out.
Cool, I hope it's this smooth. I don't want to add a ton of people to my friends list just for GTA V.
