what would it be? would it be a fave character or a weapon or some cool gadget? i would bring out alot of the halo weapons even though id ont play halo the weapons look like they would be badazz
My vote goes to jewelry. Amulet of Kings from TES IV so I can turn into acatosh.
Sorry to ruin that thought for you but the Amulet of Kings today(or rather 3E 433) *can only be worn by someone of the Septim bloodline so unless your a Septim the amulet is only good for displaying or selling it for some major cashola. Anyways I'd bring back the hidden blade from Assassin's Creed since it looks cool as a gauntlet and is a pretty good weapon.
*In my view Mankar Cameron was able to wear the amulet because he controlled Paradise and made it so he could wear it.
probably the freedom. there is much more freedom in games then real life. by that i mean doing what you want to AND physical freedom that is imposibble like flying/jumping high/casting magic etc. those soecial abilities are what makes games so fun
