Although I'm not a huge fan of GTA I'd say they need to put all the features they removed back in.

Miis replacing realistic people (at least in the Wii version)

gambling.....all kinds

Second this!

- An european based city.
- For the controls to not feel so heavy and clunky. Nico is sometimes a chore to move. He almost runs like a tank would. Hiding and shooting to feel lighter and easier to actually do.
- The setting should not be ultra realistic. Uncharted isn't and it only did it good. Art design is very important.
- Surprise me. Killing, maiming, running over, etc, has been done to death. Pass the pun.

Some nice ideas there guys. I would like to see the stuff from San Andreas put back in alongside more gambling (hadn't thought of that myself).

I would like to see pointless features removed (like going to the gym) and a map confined to a city (ie. no surrounding area).

A streamlined GTA ala-Vice City is the best GTA in my opinion.

i want a story-driven open world game, with a strict linear path, that advocates pacifism by shooting people in the head!

oh, and i want to see houses!

..and fish!

I've wanted to see this in the next GTA every single time, and they never deliver. It's very simple Rock Star.

1) People with shopping carts full of cans and bags and groceries, so crap flies everywhere when I crash into it.
2) People carrying giant panes of glass down the street, so glass flies everywhere when I crash into it.
3) Busy alleys and marketplaces with tons of crates and chickens, so feathers fly everywhere when I crash into it.
4) Somebody with a baby carriage, so a baby can fly everywhere when I crash into it.

I have wanted to drive through all that stuff since GTA 3 and they would be very simple to add. But here are some more:

5) People moving. Vans, trucks, couches, furniture, all stacked up outside an apartment. You can crash into it, or blow it up. Ya know, stuff that actually happens in cities? Have these guys ever lived in one? I see that every single day.
6) Cops pulling OTHER people over for traffic violations. I see that every single day.
7) Groups of people, for any reason. GTA games always have everybody alone and just wandering aimlessly. I want to drive through a park and bump into a kid's birthday party with a moonbounce, or a wedding, or a funeral, or just... something. People get together and do things in real life. You should be able to find a party, crash it, and just eat some of their food or something. Or drive through it.
8) Parades or protests. Streets blocked off every once in a while.
9) Families walking together, or couples holding hands. And when it gets late at night, lots of young people walking around.
10) More bums.

AND... put back everything you took out. And make a game for the Wii if you like money. If you make one for the Wii and do just 3 of my 10 points, I'll buy it.
