Grand Theft Auto IV Hype Factory: now open!

Grand Theft Auto IV is out on PS3 on 19th October 2007.
What we want to see in the new game starts here:
"I'd rather have a smaller, fully realised game world with every interior explorable than an enormous San Andreas with less to do." - Rich 12/08/2006
"Animals! It would be cool if people walked their dogs and you could ride horses. You could run over cats too. Roadkill!" - Tom 12/08/2006
"Heavy weather effects. Storms, snow and that. Random natural disasters would be a nice touch." - Joe 09/08/2006
"You should be able to use public transport, I don't mean steal it actually catch it. It needs hot air baloons and zeppelins too." - Tom 12/08/2006
"I want a female protagonist for once, let's trade testosterone for some oestrogen, yeah? Oh, and skateboards should be in there too. They'd add some opportunity for Tony Hawks style trick bustin'" - Joe 12/08/2006
