Why do people want to merge all the old games into one big one? I mean don't you want something different? London i think would be too liberty city like, its mainly just city and other things.
What i loved about San Andreas was it was like a City/Country/Seaside/Desert, it was a really nice environment. Mount Chilliad was also a very nice addition plus the ghost towns in the badlands.
Which leads to my conclusion:
I know that most of you want a real country and everything but honestly, wouldn't that be kind of boring? I think they should have an Australian style because it is much like san andreas theme. Roaming from Badlands, to the Country Side, and then to the City and maybe even the beach.
No I am not Australian nor do i live there but i just love the idea like this. and as i saw mentioned earlier on in another topic that GTA IV might be 3x the size of san andreas! Maybe a bit too big but 2x would be a nice touch i think.
This is my first comment too!
