Just got it but much more challenge and more tougher than GTA 3.
It's looks very realistic game, also if you trying attack on people then it's take little while and hard to beat them, even you never know if police is on behind of you then you are busted. GTA 4 seems like massive move away from GTA 3 because GTA 3 is more easier to beat but quietly hard on some missions and GTA 4 is alot more harder than GTA 3, such as control seems slowly and different.
When you are start to this game, you will be in one island since all others are blocked by police or ro*******, if you passes it then you will get 6 stars on warning level, ugh and that's new experience for me and that's not like Saints Row about all area are opened to you at first time than just limited free roaming.
