Here's my thoughts *so far*.
Thankfully didn't have to sign my life away to Rockstar on this one (apparently, from what I've heard, they asked journos - in the UK at least - who were reviewing it to give them their IP address for white-listing - typically, most companies only ask for PSN or XBL GTs so they can prevent bans being passed down in case Sony or MS think they're playing a pirated game) and got the game early via Amazon's fuck-up on Saturday.

Despite the huge world (more on that in a second), it also can be a small world on occasion, as the game can have one character run into another in LS. One such example (the only example I’ve seen since I started playing on Saturday) was Michael being in a clothes store in Rockford Hills. Just as I’m coming out, Trevor spots me (it probably helped I took him to the same store before taking Michael there) and asks me if we should hang out – I declined his invitation.
Haha, it sounds like this game has
Social Links. In fact, i'm really getting a Persona 3/4 vibe
