What is your favourite open world game?

Just Cause 2
Haven't played very much single player, but trolling in the MP mod is a ton of fun.

The Opened World. . .dunno if y'all heard about it.It's huge in Japan tho.;)

Real Life

Morrowind

I like GTA.

1) GTA Series

2) Watch Dogs

3) Far Cry Series

4) Arma Series

5) Rust

6) DayZ Mod And Game

Probably Fallout 3.

Fallout 3 hands down.

San Andreas would probably be my favorite. Fallout 3/NV would be my next choices. So many hours spent just exploring around.

edit: Burnout Paradise was pretty fun as well. :-)

Dayz, but i have only mod :/

Currently Test Drive Unlimited 2, but when it comes out: The Crew!

Kerbal Space Program

Saints Row 2

GTA3

Jak and Daxter. or is that too old?

Sleeping Dogs!

Skyrim was awesome to me

total overdose

Well, I like Skyrim/AC/SR and such but not precisely because of the open world.
So I think I will go with the Sleeping Dogs. :)

Mine are

• Grand Theft Auto series
• Saints Row The Third
• Assassins Creed Series

And that is my list, because i haven't played much others.

GTA Vice: Girls, Guns, Drugs and metal music. It's a really old game... old but gold.

Burnout Paradise

Skyrim for sure, and Fallout 3 was pretty good.

My favourite (in co-op at least) is Mercenaries 2. The developers really understood that huge explosions and rag-doll physics are a great combination. If you haven't played it, check it out.

1. The Elder Scrolls V: Skyrim, without a doubt.

2. Batman Arkham City

3. Burnout Paradise

4. Tomb Raider (2013) counts as such I think?

5. Deus Ex Human Revolution probably doesn't count as Open World... so I'll go with Watch_Dogs for the fifth place.
