Number 5 is Alive

The buses almost always have advertisements on their sides.  I could not help notice the ones advertising Grand Theft Auto V.

[Most of the buses have individual posters.  This is the collage version.]

Why?  Aside from there being so many of them, I found it odd that they had to spell out the "FIVE" within the "V".   (I wonder whether this is for the benefit of the kids that play the game before they learn their Roman numerals.)

On the day I had taken the Grand Theft Auto photo, the next bus had this -- Forza 5.  

I therefore conclude that Hindu-Arabic numerals are more straight to the point and that there are way too many people playing games (for both these games to get to version five).
