I've played nearly 7 hours now, just done the first few missions with Trevor, but spent a lot of time with him just exploring.
This is one of the best games I've ever played, there's just so much to do, everything plays out so well, the shooting mechanics, the driving (it's growing on me now), it's just all brilliant.
Visually the game is stunning as well. Driving down the freeway with the sun setting is amazing. I can't believe some people have complained about framerate as well, it's been perfect no matter what I have done.
It's just a magnificent game which I have no doubt I'm going to sink many hours into.
Oh, I also love the new wanted system!
Couple of things i don't like, the rubbish FPS in fast moving scenes, and the 3 playable characters i would rather there just be one.
Whilst I don't expect everyone to like the character switching, I personally think it's one of the best things about the game. It brings so much more to it, I bloody love it!
I'm not just being a fan boy, I was so hyped for this and was worried I'd be disappointed, but it's exceeded my expectations, which I didn't think was possible.
I don't want to go to bed and I don't want to work tomorrow
EDIT: Oh, and the water is amazing!
