If you could have any item from a video game...

A dinosaur.

Loadsa money

or a time machine

All of the weapons/in-game items from Bastion.

I mean fuck, who wouldn't want a potion that heals you instantly or 2 pistols that you can shoot even if you have no experience!

I would choose the Notepad from Scribblenauts ofc :D

Portal gun!

A pawn from Dragon's Dogma. Nothing like a slave that will eventually become you.

I'd want the hand knife from Assasin's Creed. No, not for killing anyone, but for making sandwiches all the time. Imagine, how badass it would be.

Low Orbit Ion Cannon

One more life.

DotA's Heart of Tarrasque, lets get almost unkillable!

Squall's gunblade
or the ocarina of time

Tony's mask from hotline miami.

Hintbook from Fallout 2. I officially win over all above entries :<>

Actually ther are too many things that I can't choose which. I'll settle for a box stars from Mario games.

Portal Gun, ofc.

The spoon from FFIV

D6 from binding of Isaac.

Zora's tunic - How badass would that be

harry potter's wand :P

Portal Gun, Lightsaber, Gravity Gun, Pipboy, Nanosuit, Daedric Armor + Weps, and last but not least... Shadowmere...
