Add alternative names to an existing game title

Add the option for users to put alternative names to a game already listed to prevent another user from creating and repeating the same game by mistake or not finding the game when searching.

Examples:

"Root Letter" and "√Letter"
"Sonic the Hedgehog" and "Sonic 1"
"Sonic the Hedgehog 2" and "Sonic 2"
"Teenage Mutant Ninja Turtles" and "TMNT"
"Skate" and "S.K.A.T.E."
"NERO Nothing Ever Remains Obscure" and "N.E.R.O."
"Alien³" and "Alien 3"
"FEAR 3" and "F.3.A.R."
Clive Barker's Jericho" and "Jericho"
"Mark McMorris Infinite Air" and "Infinite Air"

In other words, to be able to add how they are also better known or a.k.a.

I create this post because of the duplicate that I found here with "Mark McMorris Infinite Air" and "Infinite Air" I am almost 100% sure that a user duplicated it by not finding the game with any of the 2 names

Thank you very much for reading this
