What really gets me, is the amount of additional love (attention to detail) that Rockstar has given, is head and shoulders beyond any game out. I mean, I thought Forza had a great online system, where you can share photos, replays and the such. GTA V goes above and beyond, for crying out loud, it has a freaking real Stock Market!!
I mean GTA Online isn't even out yet, so I can only imagine how its gonna be after that. But right now via the single player, you can upload your cell phone pics in game to the Rockstar social club, (I'm looking at a bunch of 'selfies' from the main characters online right now) and share and comment on them online. The Social club even tracks your progress online ala Halo! I also love that you can tag songs from the radio station and then listen to the songs on the web via Spotify. This is so cool.
Sorry for the fanboy rant, but I just really appreciate the extra effort by Rockstar. If you dont have this game yet, what the hell are you waiting for, RUN!
