I think you're right. A teleporter would be bad, because we could jump directly to the friends and the loots, if somebody is standing over there. This would mean, that you faster collect your loot and lose the fun, to find the loot. But some bycicles or montainbikes would be very nice. In the reality we also can't teleport and the near realism is that, what raise the funfactor. (Thanks for your very fast answer)
