When I discovered Minecraft I lost interest in other sandboxes

terraria...
and soon¹ starbound.

¹Starbound's definition of soon may vary.

Nehrim!

Minecraft, TES series and Saints Row series :D

GTA series

i like all sandboxs

fortnite

Saint's Row the Third is just so much fun with friends.

SR3 :D

Arma series

Probably S.T.A.L.K.E.R. Shadow of Chernobyl.

Cod

Try Project Zomboid, its badass.
If you like zombie sandbox, this is the ideal game for you. They are also working on a major update thats going to make the game even more awesome.
Oh oh oh, and dont forget, multiplayer is a future feature.

When i was little my mom used to take me at a park where there was this huge sandbox with all kind of toys in it,and stuff.
Yeah that was one hell of a good sandbox

Minecraft, GTA IV, Fallout 3/NV and ArmA series.

Fable (just the first one, the others sucks)

As far as I can remember, the only sandbox games I've played so far are the Minecraft demo and Just Cause 2...

Speaking of Just Cause 2, I'm having so much fun with it. Blowing shit up for the hell of it is the greatest thing ever.

EDIT: Damnit, I forgot about Garry's Mod. Haven't played much of it yet, though.

1 Terraria, 2 Wurm Online (this is the game that minecraft is "based on"), 3 EVE online, 4 Minecraft

Duh. Minecraft. And FNV as a honorable mention.

Terraria, Minecraft and Just Cause 2.

Terraria and Minecraft xD

I believe it would be Saints Row the third. Yes, i know for the fact that this game is stupid and full of hideous idiocy made by a group of horrendous imbeciles and misfits. But i believe that would be the thing that make this video game as enjoyable as always. And that is but a mere personal opinion of course. #Personaltalklikeagentlemanday

GMOD, Fallout 3 NV, Terraria

X series.

worldsplayer hehehehe
